ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.ribosome - an organelle in the cytoplasm of a living cell; they attach to mRNA and move down it one codon at a time and then stop until tRNA brings the required amino acid; when it reaches a stop codon it falls apart and releases the completed protein molecule for use by the cell; "the ribosome is the site of protein synthesis"
cell organ, cell organelle, organelle - a specialized part of a cell; analogous to an organ; "the first organelle to be identified was the nucleus"
