Write a brief account of the contributions made by J. D. Watson, F.H.C. Crick and M.H.F. Wilkins.

In the double helix model of DNA as proposed by J. D. Watson and F.H.C. Crick, each base pair is how far from the next base pair?

The H.C.F. of 144 and 198 is

Find the H.C.F. and L.C.M. of 1152 and 1664.

Find the L.C.M. And H.C.F. or 5!,6! And 7!

The squared length of the intercept made by the line x=h on the pair of tangents drawn from the origin to the circle x^2+y^2+2gx+2fy+c=0 is (4c h^2)/((g^2-c)^2)(g^2+f^2-c) (4c h^2)/((f^2-c)^2)(g^2+f^2-c) (4c h^2)/((f^2-f^2)^2)(g^2+f^2-c) (d) none of these

Find : H.C.F. (3, 5)

Chromosomes were first seen by (a) Hofmeister (b) Waldeyer (c) Walter S. Sutton (d) Crick and Watson

The entire body of molecular biology was the consequent development with major contributions from (a) Tansley , Aristotle , Niremberg , Khorana , Kornberg , Benzer , Monod, Brenner (b) Watson , Crick Humboldt , Darwin, Kornberg, Benzer , Monod , Brenner (c) Watson , Crick , Niremberg , Khorana , Kornberg ,Ehrlich , Mendel (d) Watson , Crick , Nuremberg , Khorana , Kornberg , Benzer , Monod , Brenner

What background information did Watson and Crick have made available for developing a model of DNA ? What was their contribution ?
