WebDetermine the correctness or otherwise of the following Assertion (A) and the Reason (R). Assertion: Isopropylthiogalactoside (IPTG) is a gratuitous inducer of lactose operon. Reason: Gratuitous inducers are chemical analogs which behave like natural inducer but they do not serve as substrate for the enzymes that are subsequently synthesized. A. … WebIPTG (also known as Isopropyl-β-D-Thiogalactopyranoside) is a molecular biology reagent that functions as an inducer of galactosidase activity by binding to and inhibiting …
Web1 feb. 2024 · The possible explanation for this phenomenon is that IPTG can induce gene expression of GOI, located on a pET-based plasmid, by derepressing P T7, through binding to LacI, but simultaneously IPTG is acting as an inhibitor of the P araBAD system, which controls the expression of T7 RNAP [ 47 ].
