Question

In an analysis of the nucleotide composition of DNA, which of the following will be found?
A) A=C
B) A=G and C=T
C) A+C=G+T
D) G+C=T+A

Answer 1

Answer:

Option C

Explanation:

As per the Chargaff's Rule of Base Pairing, nucleotide base pairs are complementary to each other and the common formula of pairing is as follows –  

A member of purine (Adenine and cytosine) group pairs with the member of pyrimidine (Thymine and guanine) group

Therefore, A always pairs with T and C pairs with G as they become structurally stable by forming hydrogen bonds

Thus, Option C is correct
