- 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_forwardplease help. do 1st problemarrow_forward
- Help!arrow_forwardPls Provide what is being asked in the picture givenarrow_forwardE30. An electrophoretic mobility shift assay can be used to study the binding of proteins to a segment of DNA. In the experiment shown here, an EMSA was used to examine the requirements for the bind- ing of RNA polymerase II (from eukaryotic cells) to the promoter of a protein-encoding gene. The assembly of general transcription factors and RNA polymerase II at the core promoter is described in Chapter 12 (Figure 12.14). In this experiment, the segment of DNA containing a promoter sequence was 1100 bp in length. The fragment was mixed with various combinations of proteins and then subjected to an EMSA.
