Which of the following might be used by an E. coli cell to directly modify its metabolic activities through genetic control in response to nutrient availability?

		Nuclear pore inhibition
		The lac operon
		Protein targeting to the endoplasmic reticulum
		The spliceosome

Expert Solution

The lac operon is the genitical control of lactose metabolism in E.coli in the absence of lactose a repressor protein attaches to operator region and inhibits the gene in producing the beta galoctosidase

In the presence of lactose the repressor protein bounds to lactose and polymerase enzyme attaches to promoter Gene and gene is expressed and lactose is metabolised .

propose a mechanism by which chemotaxis is used by E. coli to move away from a repellent. In particular, think about the following: Describe the interaction between the chemoreceptors and the two-component regulatory system when dealing with a repellent What kind of flagellar movement does this cause? How can the cell detect whether it’s moving away or towards a repellent in a gradient?
