[1998, 2008]
(a) Adenine and thymine; guanine and cytosine
(b) Adenine and thymine; guanine and uracil
(c) Adenine and guanine; thymine and cytosine
(d) Uracil and adenine; cytosine and guanine
Show Answer
Solution:
- (a) In DNA the complimentary bases are Adenine and thymine;
Guanine and cytosine.
The genetic information for cell is contained in the sequence of bases $A, T, G$ and $C$ in DNA molecule.
Adenine pair with thymine with two hydrogen bonds and Guanine pairs with cytosine with three hydrogen bonds.
