WebThe intact ribosome contains three binding sites for substrate tRNAs that are termed as the aminoacyl-tRNA site (A site), peptidyl-tRNA site (P site), and exit-tRNA site (E site). These three binding sites span the interface between the 30S and 50S subunits. The central activity of the ribosome is catalysis of peptide bond formation. dj blue bird naruto dattebayoWebFeb 5, 2024 · The function of the Ribosome is to create polypeptides for excretion or use in the cell.
