Below is a description of how adherens junctions are assembled. What is a TRUE statement about the GTPases that regulate this process? Phase 1: Adherens junction assembly begins with two cells sending out protrusions to find each other. The cytoskeletal fibers supporting protrusions are branched.  Phase 2: Once they have made contact, the cells begin to recruit the necessary proteins to begin adherens junction assembly. Phase 3: As the junction expands in size, the cytoskeletal fibers supporting the junction reorganize from being branched to being parallel.

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?
