In DNA, the complimentary bases are

A

adenine and guanine, thymine and cytosine

B

uracil and adenine, cytosine and guanine

C

adenine and thymine, guanine and cytosine

D

adenine and thymine, guanine and uracil

Text Solution

Verified by Experts

The correct Answer is:
C
DNA contains two types of nitrogenous bases, i.e.,
Purine `rarr` Adenine (A), Guanine (G)
Pyrimidine `rarr` Cytosine (C), Thymine (T)
Adenine pairs with thymine `(A : T)` by two hydrogen bonds and Guanine with Cytosine `(G : C)` by three hydrogen bonds.
