WebSep 9, 2024 · September 9, 2024 by Alexander Johnson. The G1 checkpoint. The G1 checkpoint is located at the end of G1 phase, before the transition to S phase. If cells don’t pass the G1 checkpoint, they may “loop out” of the cell cycle and into a resting state called G0, from which they may subsequently re-enter G1 under the appropriate conditions. WebApoptosis is a normal developmental process in C. elegans. They found several genes involved in apoptosis, including ced−9 and ced−3. The ced−3 gene was found to promote cell death, and ced−9 to inhibit it. The ced−9 gene serves as a regulator that prevents apoptosis in the absence of a signal promoting apoptosis.
