In a DNA molecule, the phosphate group is attached to carbon of the sugar residue of its own nucleotide and carbon of the sugar residue of the next nucleotide by bonds.

Question

In a DNA molecule, the phosphate group is attached to carbon of the sugar residue of its own nucleotide and carbon of the sugar residue of the next nucleotide by bonds. (A) 5', 3', phosphodiester (B) 5', 3', glycosidic (C) 3', 5', phosphodiester (D) 3', 5', glycosidic

Tardigrade Admin · Accepted Answer

A deoxyribonucleotide of DNA is formed by crosslinking of three chemicals- deoxyribose sugar (C5H10O4), a nitrogen base and phosphoric acid (H3PO4). The backbone of a DNA strand is built up of alternate deoxyribose and phosphoric acid groups. The phosphate group is connected to carbon 5' of the sugar residue of its own nucleotide and carbon 3' of the sugar residue of the next nucleotide by phosphodiester bonds.
