Question

Certain hormones, such as epinephrine, can increase the levels of
cAMP within cells. Let’s suppose you pretreat cells with or without
epinephrine and then prepare a cell extract that contains the
CREB protein.
You then use an electrophoretic mobility shift assay to analyze
the ability of the CREB protein to bind to a DNA fragment
containing a cAMP response element (CRE). Describe what the
expected results would be.
