A

Nitrogen bases and sugars

B

Nitrogen bases and phosphate groups

C

Number of C-atoms in sugars

D

Sugar and phosphate groups

Text Solution

Verified by Experts

The correct Answer is:
A
`**" "`A nucleotide has three components - a nitrogenous base, a pentose sugar (ribose in case of RNA, and deoxyribose for DNA), and a phosphate group.
`**" "`There are two types of nitrogenous bases - Puriness (Adenine and Guanine), and Pyrimidines (Cytoine, Uracil and Thymine).
`**" "`Cytosine is common for both DNA and RNA and Thymine is present in DNA.
`**" "`Uracil is present in RNA at the place of Thymine.
