- The cell nucleus is a membrane-bound organelle that contains most of the cell's genetic material in the form of DNA.
- In eukaryotic cells, the cell nucleus plays a crucial role in regulating cell growth, metabolism, and reproduction.
- The cell nucleus is surrounded by a double membrane called the nuclear envelope, which regulates the movement of materials in and out of the nucleus.
- During cell division, the cell nucleus undergoes a process called mitosis, in which the genetic material is replicated and divided equally between two daughter cells.
- The cell nucleus also contains structures called nucleoli, which are responsible for the synthesis of ribosomal RNA and the assembly of ribosomes.
