Ribosome


The ribosome is a tiny organelle present in all living cells in thousands of copies that manufactures the protein molecules on which all life is based. It effectively operates as a highly organized and intricate miniature factory, churning out those proteins – long chain-like molecules – by stitching together a hundred or more amino acid molecules in just the right order, and all within a few seconds. And this exquisitely efficient entity is contained within a complex chemical structure that is some 20-30 nanometres in diameter – just 2-3 millionths of a centimetre.
