Study Notes
Nucleus Function and Importance
- Acts as the control center of the cell, directing cellular activities.
- Houses genetic material, specifically DNA, vital for inheritance and cell function.
- Responsible for regulating gene expression, influencing which genes are turned on or off.
- Plays a key role in cell division, ensuring genetic material is accurately replicated and distributed.
Nuclear Envelope
- Encloses the nucleus, providing a protective barrier for the DNA.
- Helps prevent damage to genetic material from external factors, maintaining cell integrity.
- Composed of two lipid bilayers, which control the entry and exit of materials between the nucleus and cytoplasm.
