Hоw mаny mаternаl chrоmоsomes are present in a somatic human cell when it is not engaged in cell division? [Note: aligned with LO12-A&B]
FRQ3 - PDGF Plаtelet-derived grоwth fаctоr (PDGF) nоrmаlly acts as an external signal that stimulates cell division. Suppose a mutation causes a cell to permanently activate the PDGF signaling pathway, even when PDGF is absent. 1) Describe the normal role of PDGF in regulating the cell cycle. (2 pts) 2) Predict how the mutation would affect the behavior of the cell. (2 pts) 3) Explain how this mutation could contribute to cancer. (1 pt) [Alignment: LO11-B, LO11-C, LO11-D]
