Question

Which one of the following is not applicable to RNA?

विकल्प

• Complementary base pairing

• 5' phosphory and 3' hydroxyl ends

• Heterocyclic nitrogenous bases

• Chargaff's rule

Answer 1

Chargaff's rule

Explanation:

Chargaff's rule does not apply to RNA. It is the generalised DNA structural formula. The rule stipulates that the DNA from any cell of an organism should have a 1: 1 ratio (base pair rule) of pyrimidine and purine base, i.e. guanine equals cytosine and adenine equals thymine.
