A ribosome is a tiny structure inside cells that builds proteins by linking amino acids together in the order given by RNA instructions. It acts like a microscopic factory for making the parts a cell needs.
From *ribo-* referring to ribonucleic acid (RNA) + *-some* from Greek *sōma* “body.” The name highlights that ribosomes work closely with RNA and are distinct little “bodies” inside the cell.
Every protein in your body—from enzymes to hair—starts on a ribosome assembly line. You have so many ribosomes working at once that your cells are like noisy factories, silently building you every second.
