Question:
In nucleoside, a base is attached at 1C position of the sugar moiety. A nucleotide is formed by linking the phosphoric acid unit to the sugar unit of a nucleoside. At which position of sugar unit is the phosphoric acid linked in a nucleoside to give a nucleotide?
Solution:
A nucleoside is formed when a nitrogenous base is attached to a 1’ position of a five-carbon sugar. Phosphoric acid is linked to the 5’ carbon of the sugar in a nucleoside molecule to give a nucleotide molecule.
