Madhur L.
An elongating ribosome is bound to appropriate tRNAs in both the A and P sites and is ready for peptidyl transfer. What happens next? A. The carboxyl end of the polypeptide chain is released from the P-site tRNA and joined to the free amino group of the amino acid linked to the A-site tRNA. B. The carboxyl end of the amino acid is released from the A-site tRNA and joined to the free amino group of the polypeptide chain linked to the P-site tRNA. C. The tRNA with the growing peptide chain is translocated to the E-site where the amino acid from the A-site tRNA will be linked to the polypeptide chain. D. The tRNA with the amino acid attached is translocated to the E-site before it is linked to the growing polypeptide chain.

Place the stages of translation in the correct order. ____ initiator tRNA leaves the ribosome ____ mRNA binds to the small ribosomal subunit ____ new tRNAs continue to bring their corresponding amino acids to the ribosome and the amino acid chain grows ____ peptide bond occurs between amino acids ____ large ribosomal subunit binds and places initiator tRNA into P-site ____ translocation occurs ____ a stop codon is reached and polypeptide breaks free; ribosome subunits separate ____ initiator tRNA binds to the start codon AUG, has anticodon UAC, and is carrying amino acid MET ____ second tRNA enters A-site and has anticodon to complement mRNA codon
