What is the significance of the nucleus?

The nucleus is an organelle that stores the majority of a cell’s genetic material and carries instructions on how a cell should function. The genes within the nucleus provide information on cellular processes such as cell division, protein synthesis, and cell growth. This is why the nucleus is also known as the control center of the cell. Nuclear transport is another significant process of the nucleus ensuring that only specific molecules are able to enter or exit the nucleus. This maintains the integrity of nuclear processes and proper functioning of the cell.
