What happens when a stop codon is reached by a ribosome? A)A termination tRNA^ter binds to the codon and is used to release the growing peptide from the P site tRNA.The ribosome then is likely to dissociate. B)A termination tRNA^ter binds to the codon and the growing peptide is transferred to it.When the peptidyl-tRNA^ter reaches the P site,the ribosome is signaled to release the protein.The ribosome then is likely to dissociate. C)A termination tRNA^ter binds to the codon and the growing peptide is transferred to it.When the peptidyl-tRNA^ter reaches the P site,the ribosome dissociates.A separate peptidyl transferase then releases the protein from tRNA^ter. D)A release factor binds to the codon and is used to release the growing peptide from the P site tRNA. E)A release factor binds to the codon and the ribosome dissociates.A separate peptidyl transferase then releases the protein from the last tRNA to which was attached.

When a stop codon is reached by a ribosome, a release factor binds to the codon, which triggers the release of the growing peptide chain from the tRNA in the P site. This process is crucial for terminating protein synthesis.
