Interestingly, the relatively simple mechanisms of gene expression in prokaryotic cells, as exemplified by the trp and lac operons, provide insight into several general principles involved in ...

Life Cycle Of Operons Yields New Look At Bacterial Genetics Date: July 6, 2006 Source: Lawrence Berkeley National Laboratory Summary: In a breakthrough that will immediately benefit biologists who ...

Mystery of operon evolution probed Date: August 30, 2012 Source: Rice University Summary: New research suggests a possible explanation for the organization of operons, jointly controlled clusters ...

Operons, clustered groups of co-expressed genes, are well known in prokaryotes, but few examples exist in eukaryotic organisms. The availability of extensive transcriptome and genomic data for many ...

Operons were first described 4 in prokaryotes — small, single-celled organisms without a nucleus. In these organisms, genes needed for one particular process (say, synthesis of an amino acid ...

Berkeley, CA -- In a breakthrough that will immediately benefit biologists who study bacteria, a team of researchers has determined the life cycle of operons, small groups of genes with related ...

Prokaryotic genes are clustered into operons, each of which code for a corresponding protein. In prokaryotes, transcription initiation is the main point of control of gene expression.
