Research into the stability of aa-tRNAs illustrates that the acyl (or ester) linkage is the most important conferring factor, as opposed to the sequence of the tRNA itself. This linkage is an ester bond that chemically binds the carboxyl group of an amino acid to the terminal 3'-OH group of its cognate tRNA. It has been discovered that the amino acid moiety of a given aa-tRNA provides for its structural integrity; the tRNA moiety dictates, for the most part, how and when th… WebA peptide bond forms between the amino acid attached to the tRNA in the A site and the growing polypeptide chain attached to the tRNA in the _____ site P The ribosome moves along the mRNA so that the tRNA that was in the _____ site is now in the P site and the tRNA that was in the P site is now in the E site. prowarm egg crateWebMar 20, 2024 · The amino acids are loaded onto the tRNAs by specialized enzymes called aminoacyl tRNA synthetases, usually with one synthetase for each amino acid.
