Nucleotide
A nucleotide is a repeating unit in a DNA or RNA chain. It consists of a sugar (ribose RNA, deoxyribose DNA), which has a base attached to its 3' end and a phosphate chain attached to its 5' end.
Nucleoside
An organic molecule, consisting of a base (deoxyadenosine, deoxyguanosine, deoxycytidine, deoxythimidine) and a 2' deoxyribose.
If a posphatechain is added, it becomes a deoxynucleotide.
