Can you explain?
E27. A cloned gene fragment contains a regulatory element that is recog-
nized by a regulatory transcription factor. Previous experiments have
shown that the presence of a hormone results in transcriptional acti-
vation by this transcription factor. To study this effect, you conduct a
electrophoretic mobility shift assay and obtain the following results:

- protein. You create a mouse line with Cas9 under control of a brain-specific enhancer, while the short guide RNA complementary to the first exon of Gene Y is expressed in all tissues. You subsequently sequence Gene Y in both brain and liver tissue. What would expect in each tissue? You can assume that the CRISPRICas9 system will impact both copies of Gene Y in cells, and that the first exon of Gene Y is necessary for Gene Ys function. a.

What scenario best describes, what occurs during this type of mutation, causing cells to proliferate abnormally? Chromosomal translocations may place the gene downstream near the promoter region, therefore causing over-expression of the gene The gene may be placed in the transcription start site, downstream of the gene, initiating transcription by recruiting polymerase II Translocation mutations will initiate the transcription of mRNA in the cytoplasm of the cell catalyzing protein synthesis. Chromosomal translocations can sometimes place a gene under the control of a powerful enhancer, upstream.arrow_forward
