Question

According to base pairing rules, cytosine always pairs with which base in an equimolar relationship?

विकल्प

• Guanine (G = C)

• Uracil (U = C)

• Adenine (A = C)

• Thymine (T = C)

Answer 1

Cytosine exclusively pairs with guanine through hydrogen bonding in DNA. Since each cytosine forms a base pair with exactly one guanine, they are equimolar and the relationship is expressed as G = C.
