Wilms tumor 1, or nephroblastoma, is caused by mutations in the WT1 gene, which encodes a transcription factor. You have identified a novel variant in WT1: Arg422Pro. You have control cells and cells that have been engineered to carry the homozygous WT1 p.Arg422Pro mutation. You want to assess effects of this mutation on a variety of endpoints. For each endpoint listed below, choose the one technique is best suited to answer the question. Choose from: array CGH, qRT-PCR, qPCR, RNA-seq, FISH, in situ hybridization, western blot, immunostaining, WT1 ChIP-seq, WT1 ChIP-PCR, ATAC-seq, 3C Endpoint Technique? WT1 protein amount (quantitative) Western blot WT1 protein binding to all enhancers, genome-wide Chip-seq WT1 mRNA amount (quantitative) WT1 protein subcellular localization Quantitative assessment of all mRNAs in these cells (genome-wide) RNAseq Chromatin interactions between a specific WT1 chromatin binding site (identified above)…

. 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 containing missense mutations in the crp gene(encoding the positive regulator CRP) are Lac−, Mal−,Gal−, etc. To find cells with suppressors of the crpmutation (that is, cells with the crp mutation thatbehave as if they are crp+), cells were screened tofind those that were both Lac+ and Mal+.a. What types of suppressor mutations would youexpect to obtain using this screen compared with ascreen for Lac+ only?b. All suppressors isolated were mutant in the genefor the α-subunit of RNA polymerase. What hypothesis could you propose based on this analysis?

The chart below is a position specific scoring matrix (PSSM, a logarithmic transformed matrix) for a transcription factor binding site. (1). Evaluate a sequence “GACATTCA” to find out which segment of the sequence fits the binding site best. (2) What is the max score that a sequence can have with this PSSM? (3) What is the minimum score a sequence can have with this PSSM?
. An interesting mutation in lacI results in repressorswith 110-fold increased binding to both operator andnonoperator DNA. These repressors display a “reverse”induction curve, allowing β-galactosidase synthesis inthe absence of an inducer (IPTG) but partly repressingβ-galactosidase expression in the presence of IPTG. Howcan you explain this? (Note that, when IPTG binds a repressor, it does not completely destroy operator affinity,but rather it reduces affinity 110-fold. Additionally, ascells divide and new operators are generated by thesynthesis of daughter strands, the repressor must findthe new operators by searching along the DNA, rapidlybinding to nonoperator sequences and dissociating fromthem.)
