Functions of Ribosomes

Functions of Ribosomes - Ribosomes take part in protein synthesis. Two or more ribosomes simultaneously engaged in protein synthesis on the same mRNA strand form polyribosomes.

The ribosome functions as a template, bringing together different components involved in the synthesis of proteins.

Interaction of the tRNA-amino acid complex with mRNA, which brings about translation of the genetic code, is coordinated by the ribosome.

Ribosomes also have a protective function. The mRNA strand which passes between the two subunits of the ribosome is protected from the action of the enzymes of the nucleus (nucleases).

Similarly the nascent polypeptide chains passing through the tunnel or channel between the subunits are protected against the action of protein digesting enzymes.
