What is the function of the ribosome in the polypeptide synthesis?

The ribosome plays a crucial role in polypeptide synthesis by serving as the site where messenger RNA (mRNA) is translated into a polypeptide chain. It facilitates the decoding of mRNA sequences into corresponding amino acids, which are brought in by transfer RNA (tRNA) molecules. The ribosome assembles these amino acids in the correct order, forming peptide bonds to create a growing polypeptide chain. This process occurs in two main stages: initiation, elongation, and termination.
