Differentiate between nucleoside and nucleotide:

Explanation

Ans: Nucleoside- A nucleoside coatains ouly two basic components of nucleic acids, i.e., it pentóse sugar and a nitrogenous base. It may be represented as sugar-base. 'x^2'
Depending upon the type of sugar present, nucleostidestare of two types:
(i) Ribonucleosidcs and
(ii) Deoxyribơnucleosides. Nucleotides - A nucleotide contuins 'd D' tbe three basic components of riueleic acids, 'i, epsilon', a phosphoric acid' group, a"pentose, sugar and a nitrogeneous base. In other words. nucleotides sre, nuclepside monophosphates. Depending upan the type of sugar present, niucleotides like nucleosides are of two types:
(i) Ribonucleotides and
(ii) Deoxynucico tides.
