Question

A nucleoside differs from a nucleotide in not
having
(a) phosphate
(b) sugar
(c) nitrogen base
(d) phosphate and sugar

Answer 1

Answer:

the required answer is (a)...

Answer 2

Answer is option 'a'

Explanation:

• A nucleoside varies from a nucleotide in not having a phosphate group.
• A nitrogenous base is joined to the pentose sugar by an N-glycosidic linkage to shape a nucleoside, i.e., Nucleoside=Nitrogen base Pentose sugar.
• At the point when a phosphate bunch is joined to the 5'- OH of a nucleoside through phosphodiester linkage, a nucleotide is shaped, i.e., Nucleotide = Nitrogen base+ Pentose sugar +Phosphate (PO4). In this way, a nucleoside varies from a nucleotide as it does not have the phosphate group.
• Hence, the right answer is option a " phosphate".
