A cloned gene fragment contains a regulatory element that isrecognized by a regulatory transcription factor. Previousexperiments have shown that the presence of a hormone resultsin transcriptional activation by this transcription factor. To studythis effect, you conduct an electrophoretic mobility shift assayand obtain the following results: Explain the action of the hormone.
. In an effort to determine the location of an operator sitefor a negatively regulated gene, you have made a seriesof deletions within the regulatory region. The extent ofeach deletion is shown by the line underneath the sequence, and the resulting expression from the operon(i = inducible; c = constitutive; − = no expression) isalso indicated....

Why do you think deletions 2 and 4 show no expression of the gene?
Cells go to great length to correctmistakes in the processes of DNAreplication, transcription, splicing,and translation. Are there analogousstrategies to correct mistakes in theselection of which genes are to beexpressed in a given cell type? Couldthe great complexity of transcriptioninitiation in animals and plants reflectsuch a strategy?
Proto-oncogenes can be converted to oncogenes in a numberof different ways. In some cases, the proto-oncogene itselfbecomes amplified up to hundreds of times in a cancer cell.An example is the cyclin D1 gene, which is amplified in somecancers. In other cases, the proto-oncogene may be mutatedin a limited number of specific ways, leading to alterations inthe gene product’s structure. The ras gene is an example of aproto-oncogene that becomes oncogenic after suffering pointmutations in specific regions of the gene. Explain why thesetwo proto-oncogenes (cyclin D1 and ras) undergo such differentalterations to convert them into oncogenes
You have isolated a protein that binds to DNA in theregion upstream of the promoter sequence of the sysgene. If this protein is a positive regulator, which ofthe following would be true?a. Loss-of-function mutations in the gene encodingthe DNA-binding protein would cause constitutiveexpression of sys.b. Loss-of-function mutations in the gene encodingthe DNA-binding protein would result in little orno expression of sys.
Based on its sequence similarity to Apobec1,which deaminates Cs to Us in RNA, activation-induceddeaminase (AID) was originally proposed to work on RNA.But definitive experiments in E. coli demonstrated thatAID deaminates Cs to Us in DNA. The authors of the paperexpressed AID in bacteria and followed mutations in aselectable gene. They found that AID expression increasedmutations about fivefold above the background level inthe absence of AID expression. More importantly, theyfound that 80% of the induced mutations were G→A orC→T. Does this fit with your expectation if AID-inducedmutations arose by deamination of C to U in the DNA?
Indicate whether the protein binds directly or indirectly (assuming it does) to DNA and whether to the enhancer or promote 1.) TATA box binding protein (TBP), Repressor, and Basal factors
Suppose that you have cancer cell line X was treated with drug Y toincrease the expression levels of protein Z which is a tumorsuppressor gene. (no need for this qustion)Explain How can you study protein Z in these cells? (needed)
During certain stages of development, the requirement forcertain gene products may require gene amplification. Whatpurpose does gene amplification serve?
Many genes whose expression is turned on by DNAdamage have been isolated. Loss-of-function mutations in the lexA gene lead to the expression of manyof these genes, even when there has been no DNAdamage. Would you hypothesize that LexA protein isa positive or a negative regulator? Why?
Researchers have successfully used gene therapy toameliorate some human genetic diseases by adding anormal gene copy to cells whose genomes originallyhad only nonfunctional mutant copies of that gene.For example, a form of blindness due to the lack of asingle protein called RPE65 has been reversed byintroduction of a normal RPE65 gene to cells of theretina of adults.a. The success of this gene therapy approach providesus with clues about the role of the RPE65 proteinin the retina. Do you think that RPE65 is neededfor the proper development of the human eye?b. Can you see a potential difficulty in applying this genetherapy approach for diseases like microcephaly?
