Question

Which are the structural unit of nucleic acid

Answer 1

Answer:

The sugars which are present in the nucleotide are ribose or deoxyribose. The nitrogenous bases are purines and pyrimidines. The phosphate is present as phosphoric acid. The nucleotide is formed by the union of a phosphate group with a nucleoside. The two nucleotide is linked by the phosphodiester bond. It is formed by the linkage between the 3' carbon atom of one sugar molecule and the 5' carbon atom of another. It is the basic structural unit of the nucleic acid.
