n : organelle in the cytoplasm of a living cell that is composed of ribonucleic acid; "the ribosome is the site of protein synthesis"

WordNet 2.0

1. an organelle in the cytoplasm of a living cell; ribosomes attach to mRNA and move down it one codon at a time and stop until tRNA brings the required amino acid; when a ribosome 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"

Ribosome Definition from Encyclopedia Dictionaries & Glossaries
English Wikipedia - The Free Encyclopedia
The ribosome () 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. Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and a variety of proteins. The ribosomes and associated molecules are also known as the translational apparatus.

One of the minute granules free in the cytoplasm or attached to the endoplasmic reticulum of a cell, containing a high concentration of RNA.

A cytoplasmic organelle<!-- (see) -->, composed of ribonucleic acid<!-- (see) --> and protein, that functions in the synthesis of protein. Ribosomes interact with messenger RNA (mRNA; see) and transfer RNA to join together amino acid units into a polypeptide<!-- (see) --> chain according to the sequence determined by the genetic code.
