Question

The light-producing genes of V. fischeri are organized in an operon that is under positive control by an activator protein called LuxR. Would you expect the genes of this operon to be transcribed when LuxR is bound or not bound to a DNA regulatory sequence? Explain.

Accepted Answer

Hello, everyone here. We have a question that says, in the availability of lactose and the absence of glucose, bacteria expressed lack chaperon genes, which encode enzymes for lactose uptake and metabolism. Black Opera is an example of so as described in the problem. Black chaperons can be turned on in the presence of particular small molecules like lactose in this example, and this is this describes an induce a ble opera on. So our answer is B induce a ble opera. Thank you for watching. Bye!
