The effect on the lac operon in a lactose medium.

Introduction:

The lac operon is the operon, which is activated in the presence of the lactose molecules. Thebinding of the allolactose causes the expression of the lac operon and the metabolism of thelactose.

Expert Solution & Answer

Explanation of Solution

In the presence of the glucose the lac operon is not active. The gene would be sitched off due to the binding of the repressor.

In the absence of the glucose and presence of the lactose, the lac operon would be activated and produce the enzyme to digest lactose in a high amount. The lactose act as an inducer.

In the absence of the glucose, the cAMP levels are high and this activated the CAP (catabolite activator protein). CAP-cAMP bind to the lac operon which causes the production of the enzyme from the lac operon.

Conclusion

In the absence of the glucose and presence of the lactose, the lac operon would be activated and produce the enzyme to digest lactose in a high amount.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
