Question

6 multiple choice 10 points what role do checkpoints play in the cell cycle? they allow cells to grow indefinitely they prevent cells from duplicating they speed up the cell division process they ensure cells are ready to divide 7 multiple choice 10 points what happens to a cell that cannot pass the checkpoints because it is irreparably damaged? it continues to divide. it becomes a cancer cell. it self destructs in a process called apoptosis. it permanently stops dividing. 8 true or false 10 points lipids are responsible for regulating the cell cycle. true false

Explanation:

• For question 6: Cell - cycle checkpoints monitor and ensure that cells have completed necessary processes and are in proper condition before progressing to the next stage of division.
• For question 7: Cells with irreparable damage that cannot pass checkpoints undergo apoptosis, a programmed cell - death process, to prevent the propagation of damaged cells.
• For question 8: Proteins and regulatory molecules, not lipids, are mainly responsible for regulating the cell cycle.

Answer:

1. They ensure cells are ready to divide
2. It self destructs in a process called apoptosis.
3. False
