Answer:

An uncharged tRNA is ejected from this site as the ribosome slides to the next codon

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 .
