[edit intro]

In biology, nucleosides are "purine or pyrimidine bases attached to a ribose or deoxyribose."^[1]

Nucleobase	Ribonucleoside (RNA)	Deoxynucleoside (DNA)
Purine nucleobases
Adenine	Adenosine A	Deoxyadenosine dA
Guanine	Guanosine G	Deoxyguanosine dG
Pyrimidine nucleobases
Thymine	5'-Methyluridine m⁵U (not present in RNA)	Thymidine dT
Uracil	Uridine U	Deoxyuridine dU (not present in DNA)
Cytosine	Cytidine C	Deoxycytidine dC

Purine or pyrimidine bases (nucleobases) attached to ribose are called ribonucleosides.

Purine or pyrimidine bases (nucleobases) attached to deoxyribose are called deoxynucleosides.

A nucleotide is a nucleoside (a purine or pyrimidine base plus a pentose sugar) with a phosphate group added.
