What happens when a stop codon is reached by a ribosome?   A termination tRNAter binds to the codon and the growing peptide is transferred to it. When the peptidyl-tRNAter reaches the P site, the ribosome dissociates. A separate peptidyl transferase then releases the protein from tRNAter.   A termination tRNAter binds to the codon and the growing peptide is transferred to it. When the peptidyl-tRNAter reaches the P site, the ribosome is signaled to release the protein. The ribosome then is likely to dissociate.   A release factor binds to the codon and is used to release the growing peptide from the P site tRNA.   A termination tRNAter binds to the codon and is used to release the growing peptide from the P site tRNA. The ribosome then is likely to dissociate.

Question

What happens when a stop codon is reached by a ribosome?

 
  1. A termination tRNAter binds to the codon and the growing peptide is transferred to it. When the peptidyl-tRNAter reaches the P site, the ribosome dissociates. A separate peptidyl transferase then releases the protein from tRNAter.

     
  2. A termination tRNAter binds to the codon and the growing peptide is transferred to it. When the peptidyl-tRNAter reaches the P site, the ribosome is signaled to release the protein. The ribosome then is likely to dissociate.

     
  3. A release factor binds to the codon and is used to release the growing peptide from the P site tRNA.

     
  4. A termination tRNAter binds to the codon and is used to release the growing peptide from the P site tRNA. The ribosome then is likely to dissociate.
