During the "s" phase of the cell cycle, DNA is duplicated. Why is this important?

• Allows for each daughter cell to be genetically DIFFERENT.

• Allows for each daughter cell to be genetically IDENTICAL

• Allows for each daughter cell to have 2X the amount of DNA as the parent cell.

• Allows for each daughter cell to have half the amount of DNA as the parent cell

Checkpoints are periods throughout the cell cycle that are controlled by ​ (a)   that ensure a proper cell division process. If a mutation occurs in the DNA that code for those proteins, then ​ (b)   is more likely to occur.

• Cyclin & CDKs
• Cancer
• Mitosis
• DNA

If a cell doesn't pass a checkpoint in the cell cycle, it will either pause and fix the problem, or undergo ___.

• Mitosis

• Development

• Apoptosis

• Cancer

Answer explanation

as a reminder, apoptosis is considered "programmed cell death." Cells will release chemicals to destroy themselves if the DNA is damaged (don't pass a checkpoint), but also if they are too old, or no longer needed for development.
