The translation is the mechanism by which coded on mRNA changes to the actual polypeptide chain. It occurs on the ribosome. The different steps involved in translation are activation of amino acids, activation of the ribosome, chain initiation, chain elongation, translocation, chain termination and modification of released polypeptide. So take this quiz and increase your knowledge about translation.
