Why does cytosine make pair with guanine...

Why does cytosine make pair with guanine and not with adenine ?

A

Polar natural of C and A

B

`C-A` pair would not reach across the double helix

C

`C-A` pair would be wider than double

D

Hydrogen bond forming functional groups are not complementary between C and A

Text Solution

Verified by Experts

The correct Answer is:
D
Cytosine make pair with guanine and not with adenine because hydrogen bond forming functional groups are not complementary between C and A.
