- noun A structure composed of RNA and protein, present in large numbers in the cytoplasm of living cells and serving as the site for assembly of polypeptides encoded by messenger RNA.

- noun 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 active site consists of RNA (white strands), not protein (orange), supporting the conclusion that the ribosome is a ribozyme.
In all, a ribosome is built from hundreds of thousands of atoms.
As the target of 50% of known antibiotics, the bacterial ribosome is a structure of major therapeutic importance.
The ribosome is a machine that gets instructions from the genetic code and operates chemically in order to produce the product.
[AY] The ribosome is so important that it is a target for many antibiotics.
This provides the most direct evidence yet that the ribosome is indeed a ribozyme, an RNA catalyst.
Other structures showed how the ribosome is inhibited by antibiotics, how it promotes the interaction of mRNA with transfer RNAs, and how the whole assembly is organized
The ribosome is an unusual catalyst, composed of three RNA molecules (four in some species) as well as dozens of proteins.
Harvard scientists have created a biological machine in the lab that manufactures proteins, mimicking the activity of a cellular structure, called a ribosome, that is critical for life.
PacBio's machine has also allowed Stanford researchers to watch the structure in cells, called a ribosome, which makes proteins from DNA code.
