WebThe ribosome has three binding sites for tRNAs: E (exit), P (peptide), and A (acceptor). Once tRNAs have given up their amino acids and are uncharged, they leave the ribosome through the E site. 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. WebMay 7, 2024 · The translation is the second part of the central dogma of molecular biology: RNA --> Protein. It is the process in which the genetic code in mRNA is read to make a protein. The translation is illustrated in Figure 6.4. 6. After mRNA leaves the nucleus, it moves to a ribosome, which consists of rRNA and proteins.
