Solution
The correct option is D 480
Nucleotides are organic molecules that serve as the monomers, or subunits, of nucleic acids like DNA and RNA. The building blocks of nucleic acids, nucleotides are composed of a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group.
In case of DNA nitrogenous bases are adenine (A), guanine(G), cytosine(C) and thymine(T), Where A pairs with T and C pairs with G. In the problem 120 A pairs with 120 T and 120 C pairs with 120 G. So the total number of nucleotides are (120A+120T+120C+120G) 480.
