In nucleoside, a base is attached at 1' position of sugar moiety. Nucleotide is formed by linking of phosphoric acid unit to the sugar unit of nucleoside. At which position of sugar unit is the phosphoric acid linked in a nucleoside to give a nucleotide?

A

purine , pyrimidine and phosphate

B

purine , sugar and phosphate

C

nitrogen base , sugar and phosphate

D

pyrimidine , sugar and phosphate

Text Solution

Verified by Experts

The correct Answer is:
C
Nucleotide is the basic unit of nucleic acids (DNA and RNA) . It is composed of nucleoside nitrogeneous base + pentose sugar) and phosphate group.
