Explanation:
During the process of translation, ribosomes play a major role in connecting mRNA codons with tRNA anticodons. Ribosomes are composed of two subunits which consist ofproteins and rRNA. The tree sites of ribosomes are:
- P site or peptidyl site-this site binds to the tRNA which holds the growing polypeptide chain.
- A site or acceptor site-this is a site of peptide bond formation between the growing polypeptide and the next incoming amino acid
- E site or exit site-the site for the final binding of t-RNA .
