During which part of the cell cycle would cancer-causing mutations (changes) to DNA occur?
The animation below shows two different cells.
What is the difference between Side A and Side B?

Which side divides faster?

Which side produces more cells?

When cells lose their ability to regulate the cell cycle, they start dividing uncontrollably. This causes cancer. Cancerous cells continue to divide and can form a mass of cells called a tumor.
Question:
Which side represents cancerous cells, AND how do you know?
Support your answer with at least one piece of evidence.

Our cells make mistakes during cell replication all the time. Luckily, the G2 checkpoint catches these mistakes before those cells become cancerous. When a cell fails a checkpoint, the cell will go through apoptosis (shown in the animation below).

Based on the animation, what happens to the cell during apoptosis?
During the G2 checkpoint, if there is an unfixable error, the cell will go through apoptosis, this is when . . .
