jgpeyer - Cool! I am interested in telomerase action too. But I rather want to study how alteration of telomere structure may influence signaling pathways inside the cell, for example, induce DNA damage response. The orchestration of telomerase action with telomere associated DDR proteins and shelterin makes this problem really interesting to study, as well as very promising as the basis for development of new therapeutic approaches.

To DDBB: Nope, I didn't heard anything yet. I hope that now, when the holidays are over, the chances to recieve the answers are becoming higher. Huh, strange that the Bio thread is so inactive this year. The formerly ones that I read here were really helpful. Astaroth: your chances are still OK. I was also rejected by UCSD on the pre-app stage. They have problems with funding and accept just as little as 1-2 internatioals per year. Honestly, I initially wasn't considering it as a real option. You should not really worry about it and concentrate on other schools. By the way, my pre-app to JHU BCMB was accepted.

Hi guys! Nice to meet the people who are in the same boat :) I'am applying for the 2009-2010 admission to PhD programs in Cancer Biology. My particular area of interest is role of DNA damage response signaling network in the regulation of apoptosis and senescence. Being an international applicant it is hard to get into the top10 schools, but if you try sometimes you get what you need, right? My stats are: BSc, biology major in Russia's top3 school. GPA: 5.0 out of 5.0. GRE Subject Biology: 920 (99%) GRE General:800Q 600V 4,0AW (A bit low, but I'am from totaly non-english medium) TOEFL: 111 (30R-28L-23S-30W) 4 years of research experience, but the area of research was far from the molecular biology (I have done 2 research projects on development of asymmetries in vertebrates, basicly morphological aspect). Have 3 personal research grants, 1 first-author publication in respected local journal, 1 article is submitted for the international journal publication (also 1-st author). Recommendations are said to be very strong: One is from PI (who knows me for 7 years!) One is from the Head of the department One is from mol bio professor.

Lime: I've focused primarily on the barrons book. I find it comprehensive + it contains the famous 3500 wordlist and nice math review. I think, it was the most helpful book in my prep. For my AWA, I have submited a couple of essays to the scoreitnow service and used barrons for tactics. By the way, I have got my scores today: 600V 800Q. It is just what I need.

Lime: Thanks for your response! Yes, I agree with you that the "art paragraph" is rather weak - I run out of time here and have only 5 minutes to write down intro and conclusion.

Hi, everyone. I'am very curious about the quality of the ScoreItNow essay evaluating service by ETS. I take it for couple of times and always recieve 5s for both argument and issue questions. How representative are these scores? Please, everyone who have taken ScoreItNow and actual GRE, tell me how neatly do your scores correspond?

My keyword here was "Still". It means that the attitude of philosophers to the character of the issue must be similar in both cases. They call attention to the problematic (difficult) approach to this problem in 17 century, and in 20 sentury they STILL think it is uneasy.

I think E is the best match.

Agree. I make a mistake when used directly used 28 to find the amount of water - it is only 80%.

Got 33,6. Original fruit contains 28p of fruit itself and 72p of water. Dry fruit still contains 28p of fruit itself + 20% water = 28*0,2=5,6. The mass of dry fruit is 5.6+28=33,6

Russia rules. Anyway. :) Regarding the essay: i've liked your examples. The structure is good and much like the one which is described in the Barrons textbook (which is an excellent manual, by the way). Of course, here are some minor grammatic flaws and literalies, like "Is is being stated that if..." "...nuances of his field, which is no more..." but these ones are accidental and, I think, will barely affect your score. Good luck!

"The best ideas arise from a passionate interest in commonplace things." Answer: At the first glance, the world consists of simple things. But all you need is just to magnify them or to look at them from a different angle to see how complicated they actually are. I truely believe that careful and persistent investigation of even most commonplace objects has allowed mankind to create it's most significant ideas. People are always looking around them. It is a kind of a natural instinct - to look around and to notice new details in old things. A lot of tecnological innovations are derived from the prototypes created by nature. Throughout the time the flight of birds has inspired humans to make a flying machine which is heavier than air. A lot of prominent thinkers have tried to solve this problem until the law of uplifting force was discovered. This is an excellent example of how the pure inspiration by such common live creatures as birds has allowed humans to overcome the earth's grasp. Modern insect-like robots, used for exploration of space, may serve as another instance of usage of usual, but elaborated natural forms for the benefit of technology. However, engeneering is not the only sphere of human knowledge where the use of common objects allow to make a significant breakthrough. Contemporary Biology is another perfect example. While being nearly purely discriptive science in the XIX and early XX century, nowadays the life science is mostly experimental. Now, it becomes clear that the most significant accomplishments of molecular biology were reached through systematical and careful examination of the most common life creatures, the so-called model objects. The persistent investigation of a single celled baceria Escherichia coli allow mankind to create artificial insulin, to solve the question of a genetic code, to learn how the species evolve etc. One famous biological proverb states: "Everything that is true for E. coli will be true for elephant as well". And that is generally true. The art has also become somehow dependent from the common things. The paintors were always inspired by the forms of nature. Even one single landscape may allow several artists to see the new facets of a common picture. Some divisions of the modern art even use common objects in their unchanged form. The simple commonplace objacts become masterpieces if we learn how to look at the from a different angle. "Even a simple bathtab can be beatiful" - think some artists. In conclusion, it becomes evident that the mankind throughout it's history have used the commonplace things as a source of inspiration and new ideas. The ideas borrowed from nature find it's application in all spheres of technology. Use of common life organisms as model objects have serves as a basis of the rise of biological science. Art has also has finded it's inspiration in common forms.

2. Given a table X - 0 1 f - n 100-n What is f? Is it frequency? Then everything is ok, answer is B.Everything which is For n = 49: There will be 49x with value 0 and 51x with value 1. So the mean will be 51\100 > 0,5.

Thanks, lime! Such a silly mistakes! I think these are mostly because of the time factor, but anyway, need to work on it. How about the general idea?

The answer in #15 is 9, by the way. Not 18.

Hi everybody! These data interpretations are just driving me mad!:crazy: I almost always get all questions right except these damned DI. I'am working through barrons and kaplan. As a rule, mistakes are about approximation - these graphs seem realy ambiguous and the answers are really close (it is common to approximate +/- one unit to get different answers :mad::mad:). Any advices how to overcome this problem?? I'am really confused, because it is really stupid to spoil a score on a most stupid type of questions...

My exam is in 4 days!!! "Governments should provide funding for artists so that the arts can flourish and be available to all people." Art is a legacy of the entire humanity. It is the basis of human culture, the personification of our moral standards. Art represents the persistence of the mankind and stimulates us for new endeavours. It is very important for governments not allow this symbol to demise because of funding issues. Throughout the time the governments have supported the art. It was impossible to create such masterpieces as Winter Palace in St. Petersburg or Golden Gate bridge in San Francisco without substantial financial supplements. Architecture always serve as a symbol of the strength of the particular country. So was in the ancient world, where the magnificent Egyptian pyramids and the monumental constructions of Rome served as a symbol of invincibility of their creators, so is in a contemporary situation. By supporting the ambitious architectural projects the government not only supports the work of individual architect, but also underscores the wealth and power of the country itself. Other, probably less expensive than architecture, areas of art also must find it’s support from government. Nowadays, the art become the area which is very dependant from the external funding sources. This is because the art itself is rarely able to deal with the costs it face solely. The rent price for studios, films and cameras, even paints and brushes become really prohibitive for most people of art. It is impossible for an artist to create a masterpiece, which can inspire the whole mankind, if he can’t barely allow himself to buy the equipment important for it’s creation. Of cause, the financing of all art projects is almost always impossible for a particular state. That’s why it is important to create system of funds allocation to certain professional communities of artists. That may help to support the most promising projects, where the artists themselves will judge which one needs more funding. Another option for art financial support is organization of art festivals and competitions, with funds as a prize for the outstanding performance. It will help not only to support a particular artist, but also will make art more public. Such festivals may become places where creative people will meet with a general public as well as with potential supporters from industry or private collectors of art. In conclusion I want to restate that the governmental support of art must become an essential issue of the country politics. While supporting the art, the government is not only supporting the creative abilities of a particular individual, but also insures the cultural development of the state itself. Such support may be organized as a direct funding of a project or as allocation of funds to a certain professional community of artists. The art festivals and competition may become the good source of merit-based funding as well as a place for presenting the projects to the common public and potential non-governmental benefactors.

6-a=6-4=2 & b-6=9-6=3 (col. B is greater) 6-a=6-4=2 b-6=8-6=2 (both r equal) Yep. But because of a+b=13 when a=4, b is always 9. And when b=8, a is always 5. So, 6-a=6-4=2 & b-6=9-6=3 (col. B is greater) 6-a=6-5=1 & b-6=8-6=2 (col. B is also greater)

1. If an integer n>2 takes the form k! And this satisfies if and only if the product of the 'n' numbers in that factorial should be less than or equal to k. Col A: n!/(n-1)! Col B: n!-(n-1)!/(n-2)! 2. Given a table X - 0 1 f - n 100-n Col A: Value of n for mean to be greater than 0.5 Col B: 50 Don't understand the questions. What do you mean by "And this satisfies if and only if the product of the 'n' numbers in that factorial should be less than or equal to k." Is it k! I got n in the column A and n-1 in the column B. So, then the answer is A. But I've done it simply solving the equations. I really don't understand the additional information. About q2 - What mean must be greater then 0,5?

7. If 2 Col A: 6 - a Col B: b - 6 Answer is B. Since a+b=13, and the maximum possible value of a is approximately 6, than b=7. 6-6

Crony: agree. I just interpret this ^ thing incorrectly. In Russia we have never used ^ symbol to define power, so I misreed such things sometimes. Luckily, they don't use them in the real test :) The answer is C. SweetDreams: why do you think that these are different numbers? IMO, these 12 can be any numbers satisfying the Σ(n1...n12) = 50. So, it could be 4 taken 11 times + 6 - then the range will be 2. But also it can be 2 taken 11 times and 28 - the rangу is 26 here. The answer is D... Nandini_bm: 10. Inequality here states, that a4. So, it is clear that a 9. I've mistaken. The answer is C - see my response to crony. 20. It's simple. a*-2 + (a*-1)6 + 9 = 0 Use the PEMDAS thing: a(-2) + (-a)6 + 9 = 0 -2a + (-6a) + 9 = 0 -2a - 6a + 9 = 0 -8a = - 9 8a = 9 a = 9/8

This triangles thing is really smart... I think, answer is D, because even (1/2 * BC)^2 + heightABS^2 = (1/2 * QR)^2 + heightQPR^2, it doesn't prove that hABS(1/2 * BC) = hQPR(1/2 * QR)... Any other ideas???

1. The value of (51!-50!)/(50!-49!)is........ 50! (51-1)/49!(50-1) = 2500/49 3. 3. How many even integers have squares between 37 and 621? 8 10 12 14 16 18 20 22 24 = 9 positive numbers + 9 negative numbers. Answer = 18 4. There is a list of 12 numbers, all are positive & even and their some is given as 50. Col A: Range of these twelve numbers Col B: 20 D. It is imposible to define the range without smallest and largest numbers. Here it could be 11 twos and a 26 and 11 fours and 6. 5. Given that, if x and y are decimals, then x+y when rounded to 100th decimal it is equal to x. Col A: y Col B: 0.007 y Answer B 6. If x & y are both greater than 0, then Col A: sqrt (10x) * sqrt (10y) Col B: 10 * sqrt (xy) Answer C. sqrt (10x) * sqrt (10y) = sqrt (100xy) = 10 * sqrt (xy) 7. Given that, if ‘x’ belongs to a set of prime numbers less than 10 and y belongs to a set of prime numbers greater than 10, then Col A: (-1)^x+y Col B: (-1)^xy D. y is always odd. x may be even (2) or odd. If both X&Y are odd - both equations result in -1. If x=2, the first equation = -1, the second one = 1. 8. If 180 is the number of ways in which letters of a word is arranged, then which of the following words can be arranged in the same number of ways? A. CABBIE B. DEBBIE B. Use the formula for permutations with repetitions: In A it will be 6!/2!=360, where 2 is number of repetitions. In B: 6!/2! x 2! = 180 - correct. 9. In a distribution of 8500 parameters, if 26.7 is 56 percentile & 37.1 is 78 percentile, then what is the percentile of x (26.7 A. 1888 B. 4750 C. 6650 & so on.... B. They ask to find the approximate number of parameter wich is closest to the (26.7 10. Given 2 Col A: a-b Col B: 4 B. As b is always > a, than a-b a-b 11. Given 'N' is a positive integer, such that when it is multiplied with 3/5 and the resultant is divided with 7/10 then its equal to which of the following A. N*(6/7) B. N/(5/2) & so on... A. 12. Given two circles that are concentric having radii 2, 5. If the tangent to the smaller circle intersects the bigger circle at ‘S’ and ’T’, then find the length of ‘ST’? It is hard for me to explain it without a diagram, but the answer is 2*sqrt21. 13. If slope of first line is -2 and other line is ½, then find the angle between the lines? Angle = 90. 14. If 0 Col A: b/a Col B: c/b D 15. A triangle with three sides were given as a = 4, b = 3, c = 6 Col A: Angle between sides a and b Col B: 90 A. 16. If n > 10000, then Col A: thousand's digit of n/8 Col B: 7 D. 17. If a parallelogram has side 16 and 10, then Col A: the area of parallelogram Col B: 155 D It can have any height. 18. If a probability of receiving a busy tone in a call is 1/3, then Col A: Call made for time probability of not receiving a busy tone Col B: 1/4 Didn't catch the question. What is 'Call made for time probability'????? 19. Col A: The units digit in 86^34 Col B: 6 B. The units digit is 4 here. 20. If a*-2 + (a*-1)6 + 9 = 0, then what is the value of ‘a’? a=9/8 21. In a total of 36 members, if 10 play chess, 16 play cricket and 20 play none of them, then what is the number of members who play any one of these games? 36 total, 20 play no games => 16 play at least 1 of them. Answer = 16 22. If -3 Col A: 1/x Col B: -3 D 23. Given A+L =130. If ‘A’ is the area of rectangle and ‘L’ is the length of the rectangle. Find the value of A? (Provided ….the breadth ‘B’ is given as 6) A = 130 - 18 4/7 = 111 3/7

As for me, the number in 50% will be mean, not median. Given this sequence of numbers, I think that 17,3 is the answer... Just as same as dome.gears said. But that's just a suggestion. About Question 2: Oh, they ask for the CLOSEST percentile! Than the answer is probably 4760 - it is closer to 4750 than 6650 to 6630... Any other ideas on that?

About the question 2: They ask to find the approximate number of parameter wich satisfy the (26.7
