Definitions:

Codons

Sequences of three nucleotides in mRNA that specify the addition of a specific amino acid into a polypeptide chain during protein synthesis.

Anticodons

The three-nucleotide sequences on tRNA that are complementary to the codons on mRNA, important for the translation phase of protein synthesis.

mRNA

Messenger RNA (mRNA) is a type of RNA that conveys genetic information from DNA to the ribosome, where it specifies the amino acid sequence of the protein products of gene expression.

tRNA

Transfer RNA; a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein during protein synthesis.
