Question

Give a brief account of the different steps involved in the translation of mRNA into a polypeptide in prokaryotes.

Answer 1

Formation of protein from mRNA is known as translation and it is also known as polypeptide synthesis. It is a unidirectional process.

The ribosome of a polygon is held together by a strand of mRNA. Each eukaryotic ribosome has two parts, smaller subunit and a larger subunit.

Largest subunit has a group for protection and passage of polypeptide, site A, it is the acceptor side, enzyme peptidyl transferase and a binding site for t RNA. The smallest subunit has a point of attachment of mRNA. Along with larger subunit, it forms a peptide transfer or donor site.

Thus ribosome help in the protein synthesis and the process is the translation.
