After the peptide bond forms, what will happen next according to the image above? a. Ribosome disassembles to release the tRNAs and allow new tRNA to enter. b. tRNA X will be carrying the polypeptide and it will shift to the A site. c. tRNA Y will be carrying the polypeptide and it will shift to the P site. d. tRNA Y will be carrying the polypeptide and it will shift to the A site. e. tRNA X will be carrying the polypeptide and it will shift to the P site.

A ribosome has a tRNA in its P site that is attached to a polypeptide. The ribosome's A site is sitting over a stop codon. What will happen next? The stop amino acid will be added to the polypeptide chain, and the polypeptide will be released. A terminator tRNA will bind in the A site of the ribosome, and the polypeptide will be released. A protein called a release factor will bind to the A site and the bond between the tRNA in the P site and the polypeptide chain will be hydrolyzed. The ribosome will shift three nucleotides toward the 3' end of the mRNA to expose the next codon in the A site

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.
