Question

What are the basic constituents of ribosomes? Explain the role of a and p sites of ribosomes in protein biosynthesis?

Answer 1

Ribosomes provide framework on which protein synthesis takes place. The mRNA binds to the 30S subunit of ribosome to form initiation complex. The main role of ribosome is its ability to catalyse the formation of peptide bonds between amino acids, so that the amino acids are incorporated into proteins.
