The ribosome (/ËraÉªbÉËsoÊm, -boÊ-/) is a complex molecular machine, found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules. Ribosomes consist of two major components: the small ribosomal subunit, which reads the RNA, and the large subunit, which joins amino acids to form a polypeptide chain.
Here various translation factors help ribosomes to translate the DNA into protein. Translation occurs in the cytoplasm. Do not get this confused with prokaryotes. In prokaryotes, they do not have organelles and so transcription and translation are coupled in the cytoplasm... (they occur at the same time).
