|
Cancer cells
|
|
|
Gametes

Al of the above
|
Explanation:
Detailed explanation-1: -stem cells. Many of the negative regulator proteins of the cell cycle were discovered in cancer cells. Thus, the correct option is (c).
Detailed explanation-2: -Cell cycle checkpoints are essential to halt cell cycle progression in response to DNA damage, thereby allowing time for DNA repair. Inhibition of CHK1 or WEE1 in cancer cells prevents cell cycle arrest during S or G2 phase and allows cell proliferation despite accumulation of DNA damage.
Detailed explanation-3: -Graphene Oxide Negatively Regulates Cell Cycle in Embryonic Fibroblast Cells.
