SSC MTS EXAM

Detailed explanation-1: -Note: Cytosine can form three hydrogen bonds with guanine, and adenine can form two hydrogen bonds with thymine. In simple words, C bonds with G and A bonds with T. This is called complementary base pairing because each base can only bond with a specific base partner.

Detailed explanation-2: -Guanine binds with cytosine in DNA and RNA and forms three hydrogen bonds. This occurs because guanine has two nitrogen atoms and one oxygen atom that are able to form hydrogen bonds, so three bonds occur between these bases.
