What is found in the nucleus that regulates the activities of the cell?

The nucleus is the control centre of the cell, and it contains genetic material in the form of chromosomes. The genes on these chromosomes are organized in such a way that they improve cell function. The nucleus regulates the activities of the cell by controlling gene expression, and it preserves the integrity of genes. RNA, ribosomes, and lysosomes are all cellular components that are involved in gene expression and protein synthesis, but they are not specifically responsible for regulating the activities of the cell in the same way that the nucleus does.
