Imagine that you are conducting experiments and you have a cell line that responds to an external hormonal signal by entering the apoptotic pathway. how would these cells respond to this hormonal signal if you could instantly and completely inactivate the bcl-2 protein? a: since bcl-2 normally protects cells from apoptosis, loss of this protein would cause these cells to go through apoptosis. b: since bcl-2 normally protects cells from apoptosis, loss of this protein would prevent apoptosis. c: since bcl-2 normally promotes apoptosis, loss of this protein would prevent apoptosis. d: none of the choices is correct.
