Definitions
American Heritage® Dictionary of the English Language, Fourth Edition
- n. A minute round particle composed of RNA and protein that is found in the cytoplasm of living cells and serves as the site of assembly for polypeptides encoded by messenger RNA.
Wiktionary
- n. biology Small organelles found in all cells; involved in the production of proteins by translating messenger RNA.
WordNet 3.0
- n. 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
Etymologies
- ribo(nucleic acid) + -some3. (American Heritage® Dictionary of the English Language, Fourth Edition)
Examples
“The active site consists of RNA (white strands), not protein (orange), supporting the conclusion that the ribosome is a ribozyme.”
“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.”
“In all, a ribosome is built from hundreds of thousands of atoms.”
The Nobel Prize in Chemistry 2009 - Illustrated Presentation
“As the target of 50% of known antibiotics, the bacterial ribosome is a structure of major therapeutic importance.”
“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.”
“This provides the most direct evidence yet that the ribosome is indeed a ribozyme, an RNA catalyst.”
“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.”
