What happens to a cell if it fails to meet the requirements at a checkpoint and the issue cannot be fixed?

The cell undergoes apoptosis (self-destruction).

Name the three phases that make up interphase and briefly describe what happens in each.

G1 (cell grows), S (DNA replication), and G2 (cell grows more in preparation for mitosis).

I can describe the main phases of the cell cycle and their purpose.

The cell cycle has two main phases: interphase, where the cell grows and replicates DNA, and M phase, where the cell divides.

During interphase, the cell cycle progresses through G1, S, and G2 phases, with checkpoints to ensure proper growth and DNA replication.

Cancer can result from cells dividing too frequently due to a failure in cell cycle regulation, potentially leading to tumor formation.

This lesson includes 10 practice questions to reinforce learning.
