Interplay of Gene Expression Noise and Ultrasensitive Dynamics Affects Bacterial Operon Organization. PLoS Computational Biology, 2012; 8 (8): e1002672 DOI: 10.1371/journal.pcbi.1002672 ...

I explained that when lactose is absent, a protein—the lac repressor, encoded by the lacI gene—binds to the operator, blocking RNA polymerase from transcribing the genes of the operon into mRNA.

“The lac operon is like the hydrogen atom of molecular biology, it’s the first system that describes gene regulation,” Xie says.

However, in most cases, researchers have only borrowed part of the lac operon system. They use the repressor protein, LacI, which physically binds DNA upstream of the gene promoter to block RNA ...

Operons are clusters of unrelated genes with related functions that are a feature of prokaryotic genomes. Here, we report on an operon-like gene cluster in the plant Arabidopsis thaliana that is ...
