Question

Which of the following is true with regards to a DNA molecule?

a) Amount of adenine is equal to the amount of guanine, and the amount of thymine is equal to the amount of cytosine.

b) The amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of uracil.

c) The amount of adenine is equal to the amount of cytosine, and the amount of guanine is equal to the amount of thymine.

d) The amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of cytosine.

Answer 1

Answer #1

In DS DNA molecule, A binds with T (with two hydrogen bonds) and G binds wtih C (with three hydrogen bonds),

so, the number of Adenince is almost same to Thymine and number of Guanine is almost same to Cytosine. simply,

A=T and G=C

So, the answer is d) The amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of cytosine.
