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 ...

The genes lacZ, lacY and lacA are transcribed from a single promoter (P) that produces a single mRNA from which the three proteins are translated. The operon is regulated by Lac repressor, the product ...

While CRISPR may be the most notable genetic technology to emerge from microbes, many of the tools researchers use to control genes and their products are borrowed from bacterial systems. One of these ...

The 92-year-old bacterial geneticist who helped pioneer the study of gene regulation has passed away. AI giant Anthropic announced the opening of a new wet lab to tackle overlooked biology problems.

This is a great little group-work activity that encourages students to use their brains to work out how the lac operon works both in the absence of and with the presence of lactose. The students are ...
