Required for the transport and metabolism of lactose in Escherichia Coli (E. coli).The lactose operon or lac operon consists of three structural genes namely lacZ, lacY, and lacA that encode proteins ...

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 ...

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 ...

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. A series of rodent experiments showed that even with abundant food and water, personal space is ...
