WebThe ribosome moves along the mRNA 3 bases at a time, from the 5′ to the 3′ direction, and new tRNAs whose anti-codons are complementary to the mRNA codons arrive with their corresponding amino acids. A peptide bond forms to join the amino acid to the carboxyl end of the growing polypeptide chain. WebThe genetic code is the set of rules used by living cells to translate information encoded within genetic material (DNA or RNA sequences of nucleotide triplets, or codons) into proteins.Translation is accomplished …

How do genes direct the production of proteins?

WebThe molecule of mRNA provides the code to synthesize a protein. In the process of translation, the mRNA attaches to a ribosome. Next, tRNA molecules shuttle the appropriate amino acids to the ribosome, one-by-one, coded by sequential triplet codons on the mRNA, until the protein is fully synthesized. 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.
