Abstract: Two mathematical models for the regulation of the lac operon are presented to study diauxic growth and non- diauxic growth on glucose and lactose. The two models take into account all of the ...

Last week I finally addressed promoters and gave a bit of background on the lac operon. Looking back, I feel that I didn't give the topic of operons adequate treatment. They are a very crucial aspect ...

Abstract: The paper describes an interactive computer program for visualizing bacterial gene regulation: the trp operon. The computer program was implemented based on our recently developed Gene Act ...

How do bacteria avoid wasteful production of unnecessary proteins when their genes are always on? The answer lies in regulating the operon. As trp levels increase, trp binds to trpR, causing a ...
