Lac (lactose) operon in a type of bacterial operon, which shows a cluster of genes that are regulated by a single promoter. It is composed of an operator, promoter, a terminator, and three structural genes (lacA, lacY, and lacZ), which are responsible for the transport and breakdown of lactose.
The lac operon is an inducible operon as it gets activated in the presence of lactose and expressed its functional genes in the form of proteins (or enzymes) for lactose metabolism.
Thus, the correct answer to be fill in first blank is 'inducible' and in second blank is 'lactose.'
The lac operon in E.coli regulates genes that code for enzymes required for breakdown of lactose. The lac operon is <span>an inducible operon </span>that is activated in the presence of lactose.
Does nature really hurt itself? does nature want to be ruined? if I would be a nature I will kick those people that have nothing to do but hurt me. Pollution is a result of human activities. it is a problem caused by many.
Accuracy refers to the closeness of a measured value to a standard or specific value while precision is the level of agreement of a particular measurement with the measured value it is repeated.
