Tutorial
Terms to Know
Elongation

When the appropriate anticodon of tRNA interacts with its codon counterpart on mRNA during translation. Elongation is the second step of translation and will continue until the stop codon is reached.

Initiation

The beginning of translation, initiation occurs by the assembly of the ribosomal subunits and when tRNA interacts with the start codon on mRNA.

Polypeptide Chain

The primary structure of a protein, a polypeptide chain is a linear chain of amino acids that are covalently bound by peptide bonds.

Termination

When the stop codon is reached during translation, translation ends and the polypeptide chain is released.

Translation

The process of “reading” a strand of mRNA and translating its message into a protein. This occurs in ribosomes and consists of mRNA and tRNA interacting with one another.
