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 functions that are ...

Operons contain multiple adjacent genes whose transcription is regulated by the transcription of a single polycistronic message. The processing of polycistronic pre-mRNA involves 3' end formation and ...

New research suggests a possible explanation for the organization of operons, jointly controlled clusters of genes that evolved in bacterial chromosomes. Operons, which are found in the chromosomes of ...

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) are ...

Amyloid is associated with debilitating human ailments including Alzheimer's and prion diseases. Biochemical, biophysical, and imaging analyses revealed that fibers produced by Escherichia coli called ...
