What is the function of the cell nucleus?
What is the function of the cell nucleus?
The cell nucleus acts like the brain of the cell. It controls and regulates the activities of the cell.
The nucleus is surrounded by a nuclear envelope that allows free passage of all molecules.

Study Notes
The Nucleus
- The cell nucleus acts like the brain of the cell.
- The nucleus is surrounded by the nuclear envelope.
- There are pores and spaces in the nuclear envelope for mRNA to pass through.
- The nucleus contains chromatin which is threads like bodies forming a reticulum and made of DNA, RNA, and nuclear proteins.
- There is a spherical round body, the nucleolus, inside of the nucleus.
- The functions of the nucleus are: 1) controlling the ongoing activities of the cell by determining which protein molecules are produced, and 2) storing the genetic information and passing it onto daughter cells during cell division.
