Question

A nucleotide is
  1. Sugar + Phosphate
  2. Base + Sugar + Phosphate
  3. (Base+Sugar+Phosphate)n
  4. Base + Sugar OH

A
Sugar + Phosphate
B
Base + Sugar + Phosphate
C
Base + Sugar OH
D
(Base+Sugar+Phosphate)n
Solution
Verified by Toppr

The correct option is B Base + Sugar + Phosphate
The sugars which are present in the nucleotide are ribose or deoxyribose. The nitrogenous bases are purines and pyrimidines. The phosphate is present as phosphoric acid. The nucleotide is formed by the union of a phosphate group with a nucleoside. A nucleoside, in fact, contains a sugar molecule along with an organic nitrogenous base.
So, the correct answer is option B.
