Witryna19 mar 2024 · The large ribosomal subunit has an overall crown-like shape, which includes the central protuberance, L1-stalk and the P-stalk . Located on the interface side of the large ribosomal subunit are the three (A, P and E) tRNA-binding sites and the PTC where peptide bond formation is catalysed. WitrynaAminoacyl tRNA synthetase is an enzyme that attaches the appropriate amino acid onto its tRNA. This step is called as the charging of the tRNA with appropriate amino acid to the anti-codon arm. The mRNA is hence attached to the tRNA and a small sub unit of the ribosome is assembled primarily which is the cellular factory that is responsible for …
