WebJan 3, 2024 · The aa2-tRNAaa2 enters the ribosome based on codon-anticodon interaction at the A site as shown below. The GDP dissociates from EF2 as aa2-tRNAaa2 binds the anticodon in the A site. To keep elongation moving along, elongation factor (EF3) rephosphorylates the GDP to GTP, which can re-associate with free EF2. WebRibosomes are the structures where polypeptides (proteins) are built. They are made up of protein and RNA (ribosomal RNA, or rRNA). Each ribosome has two subunits, a large one and a small one, which come together around an mRNA—kind of like the two halves of a hamburger bun coming together around the patty.
