Gene expression of lactose-digesting genes is controlled by the lac operon that accounts for varying amounts of lactose or ...

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 ...

1). In the 'off' state, the Lac inhibitor represses the lac operon, which prevents expression of the Tet repressor and the target gene. Additionally, a short hairpin RNA (shRNA) against the target ...

New artificial intelligence tools help scientists fight back against a rising tide of research misconduct, but is it enough?

Capsular locus for the 91 pneumococcal serotypes is between 10 and 30 kb in length and is flanked by the conserved dexB and aliA genes. The marked heterogeneity within the capsular operon has been ...
