 Dictionary entry overview: What does ribosome mean? 

• RIBOSOME (noun)
  The noun RIBOSOME has 1 sense:

1. 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

  Familiarity information: RIBOSOME used as a noun is very rare.
