Transciprtion

conversion of DNA into mRNA

Translation

Process by which mRNA is decoded and a protein is produced

Four bases of DNA

Adenine (A)Guanine (G)Thymine (T)Cytosine (C)

Purines

Adenine and Guanine

Pyrimidines

Thymine and Cytosine

Nucleoside

A base that is attached to a 5-carbon cyclic sugar via an N-Glycosidic bond.

Nucleotide

A nucleoside with a phosphate esterified to carbon 5 of the sugar.
