p53, Mitosis, and Apoptosis for Anatomy and Physiology

The video discusses DNA damage and its impact on cells, focusing on how cells respond to low and high levels of damage. Low DNA damage can be repaired, allowing the cell cycle to continue, while high damage triggers apoptosis to prevent mutation propagation. The mechanisms involve CDK2, cyclin E, retinoblastoma protein, P53, and P21, which regulate the cell cycle and DNA repair processes.

What are the consequences of high DNA damage in a cell?

What is the relationship between DNA damage and cancer development?

How does the cell ensure that mutations are not passed to future generations?

Explain the process of apoptosis as a response to irreparable DNA damage.
