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 ...
