Question

Which of the following occurs in the P site of the ribosome during translation?None of the other answer options is correct.An incoming charged tRNA binds to this site.An uncharged tRNA is ejected from this site as the ribosome slides to the next codon.The tRNA carrying the growing polypeptide moves to this site as the ribosome slides to the next codon.

Answer 1

The tRNA carrying the growing polypeptide moves to this site as the ribosome slides to the next codon.

Step-by-step 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
