Study Notes
Apoptosis: Programmed Cell Death
- Apoptosis is a form of programmed cell death.
- During apoptosis, cells activate enzymes that break down their own DNA and proteins.
- This enzymatic degradation targets both nuclear and cytoplasmic components.
- The cell fragments into smaller pieces after the breakdown.
- The term "apoptosis," meaning "falling off," describes this fragmentation process.
