Webb24 sep. 2024 · The Protein Synthesis Machinery. In addition to the mRNA template, many molecules and macromolecules contribute to the process of translation. The composition of each component varies across taxa; for instance, ribosomes may consist of different numbers of ribosomal RNAs (rRNAs) and polypeptides depending on the organism.

WebbTranslation is the process of synthesizing a chain of amino acids called a polypeptide.
