Question

The distance between two nucleotide pairs of DNA is

• A. 0.34 nm
• B. 34$\mathring{A}$
• C. $3.4\mu$m
• D. 34 nm

Answer 1

The correct option is A 0.34 nm

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. Thus, a nucleoside plus a phosphate group yields a nucleotide. The distance between two nucleotide pairs in DNA is 0.34nm.
