Charged trna and uncharged trna

WebAminoacyl-tRNA (also aa-tRNA or charged tRNA) is tRNA to which its cognate amino acid is chemically bonded (charged). The aa-tRNA, along with particular elongation factors, deliver the amino acid to the ribosome for incorporation into the polypeptide chain that is being produced during translation. WebAug 23, 2024 · The E site releases dissociated tRNAs so they can be recharged with free amino acids. The ribosome shifts 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.

The A site accepts incoming charged tRNAs and the growing polypeptide chain resides in the P site. The initiator tRNA begins in the P site. The next codon downstream resides in the A site, where the incoming charged tRNA binds.
