15.5 Ribosomes and Protein Synthesis - Biology 2e OpenStax

Ribosomes are macromolecular machines, found within all cells, that perform biological protein synthesis (mRNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) molecules to form polypeptide chains. Ribosomes consist of two major components: the small and large ribosomal subunits. Each subunit consists o… WebbThe ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA into a sequence of amino acids (a process called Translation ).
