Compare regulation by the lack repressor the trip repressor.

Short Answer

Expert verified

The lack is the gene that helps in the regulation of lack repressor, and the trip gene will help in the regulation of trip repressor.

The repressor will detach from the operator when the lack repressor will respond to the inducer. Whereas, the protein will bind to the tryptophan when the trip repressor responds to the inducer.

Step by step solution

01

lack repressor.

It will respond to the inducer which will separate the repressor from the operator.

Lack is the gene which will regulate the mechanism of the lack repressor. The lack repressor will be removed when the level of lactose increases.

02

Trip repressor.

It will respond to the inducer so that molecules of the tryptophan will bond to the protein. Trip is the gene that will regulate the mechanism of the trip repressor.When the level of trip is high, the operator will bond to the tryptophan repressor.

Most popular questions from this chapter

Why do coli cells with a defective lac Z gene fail to show galactoside permease activity after the addition of lactose in the absence of glucose?

Question: Red–green color blindness is caused by an X-linked recessive genetic defect. Hence females rarely exhibit the red–green colorblind phenotype but may be carriers of the defective gene. When a narrow beam of red or green light is projected onto some areas of the retina of such a female carrier, she can readily differentiate the two colors, but on other areas she has difficulty in doing so. Explain.

Why does the lack opera include more than one operator sequence?

Question Proliferation and diff erentiation of T and B lymphocytes during animmune response are mediated by signaling that leads to phosphorylation of a protein called IκB. Unphosphorylated IκB binds to and inhibitsthe transcription factor NF-κB. Phosphorylated IκB releases NF-κB andis then ubiquitinated and degraded by a proteasome. (a) Explain whythis mechanism for activating NF-κB allows rapid changes in gene expression. (b) Explain why directly phosphorylating NF-κB might notbe an eff ective mechanism for altering gene expression. (c) A proteinproduced by Yersinia pestis (the bacterium that causes plague) removesthe ubiquitin molecules from IκB. How would this aff ect the immune response to the Yersinia infection?

Question: Even relatively compact bacterial genomes include some noncodingDNA between genes; large eukaryotic genomes are mostly noncoding DNA. How have genome comparisons helped identify noncoding sequences that have some biological function? Have the functions of any of these sequences been identified? Where are such sequences located?
