Certain hormones, such as epinephrine, can increase the levels ofcAMP within cells. Let’s suppose you pretreat cells with or withoutepinephrine and then prepare a cell extract that contains theCREB protein.You then use an electrophoretic mobility shift assay to analyzethe ability of the CREB protein to bind to a DNA fragmentcontaining a cAMP response element (CRE). Describe what theexpected results would be.

Can you please help me by drawing a serie of schematic figures that demonstrates the information in the paragraph below. The carboxy terminus of the p53 protein acts as an allosteric regulator of sequence-specific DNA binding. This was demonstrated initially by Hupp et al. (1992) using a bacterially expressed protein. Recombinant bacterial p53 bound poorly to DNA, and binding could be enhanced by the addition of antibodies specific to the C-terminal region of the protein. Phosphorylation of Ser315 and Ser392 within this domain also enhance sequence-specific DNA binding. Dephosphorylation of Ser376 of p53 after IR allows the association of 14-3-3 proteins with the C terminus of the protein (Waterman et al., 1998). Stavridi et al. (2001) demonstrate that this interaction is required for p53 to activate the downstream gene, p21waf1/cip1, and for the G1 cell cycle checkpoint arrest response. Interestingly, this dephosphorylation event seems to be ATM-dependent, possibly by a phosphatase…

Often, the physical characteristics of genetically identical twins become increasingly different as they age, even at the molecular level. Explain why this is so from the point of view of epigenetics.
