As the cell progresses through G1, depending on internal and external conditions, it can either delay G1, enter a quiescent state known as G0, or proceed past the restriction point. DNA damage is the main indication for a cell to "restrict" and not enter the cell cycle. The decision to commit to a ne… 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. orchestra blouson garçon
