Chemical structure of a nucleotide
WebApr 7, 2024 · Nucleotides are organic molecules that act as the building blocks of both DNA and RNA. These molecules have three components – a nitrogenous base, a pentose sugar and a phosphate group. The nitrogenous bases are of two types – purines and pyrimidines. The purines are adenine (A) and guanine (G), while the pyrimidines are cytosine (C ...
