Transcription and RNA Processing

ID #1798

When the amino acid becomes attached to the attachment site of the tRNA, what happens at the biochemical level?


Energy from ATP hydrolysis is used to covalently link the carboxyl group of an amino acid to the 2' or 3' OH group of the adenine at the 3' end of the tRNA molecule. Potential energy is now stored in this tRNA/amino acid bond, which will be released and used during peptide bond formation when this particular charged tRNA participates in the elongation phase of translation.
