14.Which of the following forms the long polymers of DNA? A. Amino acids B. Ribonucleotides C. Monosaccharides D. Deoxyribonucleotides
Option D A phosphate group is linked to the nucleoside by phosphodiester linkage to form a nucleotide at 5' – OH group. 3' - 5' phosphodiester linkage connects two nucleotides, therefore it forms a long polymer called DNA. Adenine, guanine, thymine, cytosine, and uracil are the nitrogenous bases that are present in the DNA.
