WebbRibosomes are the macromolecular machines that are responsible for mRNA translation into proteins. WebbThe ribosome moves along the mRNA, one codon at a time, catalyzing each process that occurs in the three sites. With each step, a charged tRNA enters the complex, the polypeptide becomes one amino acid longer, and an uncharged tRNA departs. This and subsequent steps in the synthesis of the polypeptide are called the elongation phase of …
