1. Nucleotide is a unit which consists of a sugar, phosphate and a base. Nucleotides are basic units of nucleic acids.
2. The nitrogen base and a sugar form a nucleoside. In a nucleoside, nitrogenous base is attached to the first carbon atom (C-1) of the sugar and when a phosphate group gets attached with that of the carbon (C-5) atom of the sugar molecule a nucleotide molecule is formed.
3. The names of all nucleotides are:
| Base | Nucleotides of RNA | Nucleotides of DNA |
| Adenine | Adenylate | Deoxydenylate |
| Guanine | Guanylate | Deoxyguanylate |
| Cytosine | Cytidylate | Deoxy cytidylate |
| Thymine | ..... | Deoxythymidylate |
| Uracil | Uridylate | ........ |
