Question

A single nucleoside consists of________


  1. Sugar + Nitrogenous base

  2. Nitrogenous base + Phosphate group

  3. Sugar + Phosphate

  4. Sugar + Nitrogen base + Phosphate


Solution

The correct option is A

Sugar + Nitrogenous base


A nucleoside has two components - a pentose sugar (deoxyribose in DNA and ribose in RNA) and a nitrogenous base. When a phosphate ion gets attached to the sugar, the entire unit is called a nucleotide. So, the difference between the nucleoside and the nucleotide lies in the presence or absence of phosphate ion.
