In messenger RNA, what does each codon specify?


Quick Answer

In messenger RNA, each codon specifies for an amino acid. Amino acids are the building blocks of proteins. Messenger RNA codons code for a total of 20 amino acids as well as three stop sequences that halt synthesis of a protein.

Full Answer

Each codon on messenger RNA is a series of three nucleic acids. Nucleotides may be guanine, cytosine, adenine or uracil. Together, the triplet set of nucleic acids code for a specific amino acid. For example, the triplet set of AUG, which are the nucleotides adenine, uracil and guanine, respectively, correspond to the amino acid methionine. There are a total of 64 possible codons.
