Question

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 chian.
(D) The tRNA with the amino acid attached is translocated to the E-site before it is linked to the growing polypeptide chain.

Answer 1

The answer for this is C
