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 ...

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 ...

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.

Because the β-galactosidase activity of exponentially growing cells is at steady state, the corresponding β-galactosidase synthesis rate is derived from Equation 2. The curves in Fig. 1 show that to a ...

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 ...

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 ...

This resource is a lesson with activities covering the Lac operon content of the A Level Biology specification. This resource includes: 1: A power point to lead students through the lesson (includes a ...
