|
|
|
it allows cell division to occur indefinitely if there is an error in the cell cycle.
|
|
|
it stops the division of the cell until errors can be corrected.
|
|
|
it plays no role in cancer prevention.
|
|
|
it prevents tumors by allowing the cell to continue with cell division.
|
Detailed explanation-1: -Tumor suppressor genes are normal genes that slow down cell division or tell cells to die at the right time (a process known as apoptosis or programmed cell death). When tumor suppressor genes don’t work properly, cells can grow out of control, which can lead to cancer.
Detailed explanation-2: -Activated p53 promotes cell cycle arrest to allow DNA repair and/or apoptosis to prevent the propagation of cells with serious DNA damage through the transactivation of its target genes implicated in the induction of cell cycle arrest and/or apoptosis.
Detailed explanation-3: -How do tumor suppressor genes work to prevent the onset of cancer within cells? They synthesize proteins that inhibit the cell cycle. Tumor suppressor genes work to prevent the onset of cancer by inhibiting the cell cycle and promoting apoptosis. They synthesize proteins that promote apoptosis.
