Why is Cofilin unlikely to be found at the leading edge of a migrating cell? (Hint: The leading edge is the area of a migrating cell that is closest to the direction of movement, and therefore an area where rapid growth of actin microfilaments occurs)

Maria hypothesizes that the transcription factor DEDZ1 promotes apoptosis. She decides to design and conduct an experiment to investigate this hypothesis. Her first experiment is to use genetic engineering to knockout (delete) DEDZ1 from the genome of normal cells, and then measure and compare apoptosis in DEDZ knockout cells versus normal cells by applying Tryphan Blue to each sample.  Examine the graph of her results below. Do the results support Maria’s hypothesis?
