Question

what is the basic function of the lac operon? what is the basic function of the lac operon? to code for enzymes involved in synthesizing lactose. to produce glucose when none is available to produce lactose when none is present to code for enzymes involved in catabolizing lactose.

Answer 1

The lac operon is a genetic regulatory sequence found in bacteria that codes for the production of enzymes necessary for lactose metabolism. The operon is controlled by a repressor protein, LacI, which binds to an operator site on the DNA upstream of the genes and prevents their expression.
