The regulation of the mal operon in E. coli that involves the presence of maltose to activate gene expression is an example of positive control. In this system, the binding of maltose to a regulatory protein facilitates the initiation of transcription of the genes in the operon. Therefore, the correct response is positive control.
In E. coli cells, maltose, a type of sugar, is needed to turn on the genes that are regulated by the mal operon. This type of regulation is called(1 point)
