What is the function of the release factor during translation?

It binds to the stop codon in the A site in place of a tRNA.

It releases the amino acid from its tRNA to allow the amino acid to be added to the growing polypeptide.

It supplies a source of energy for termination of translation and the release of the polypeptide.

It releases the ribosome from the rough endoplasmic reticulum and allows the polypeptide to enter the cytosol.
