Question

Why is the nucleus called the control room of the cell?

Answer 1

Nucleus:

1. The nucleus is a pivotal organelle responsible for regulating almost all forms of cellular activities.
2. Mostly, every type of cell that exists is categorised on the basis of the absence or presence of the nucleus within its cell (categorised either as a prokaryotic or eukaryotic cell.)
3. A nucleus is defined as a double-membrane eukaryotic cell organelle that contains the genetic material.

Nucleus as the control room of the cell:

1. Because nucleus contains a material called gene which controls all activities of cell and its characteristics.​
2. Cell nuclei contain most of the cell's genetic material, organized as multiple long linear DNA molecules in complex with histones, to form chromosomes.
3. The genes within these chromosomes are the cell's nuclear genome.
4. The genes decided the types of proteins and enzymes to be formed in the cell.
5. These proteins and enzymes form the structure of the cell and do all the activities in the cell, respectively.
6. The function of the nucleus is to maintain the integrity of these genes and to control the activities of the cell by regulating gene expression—the nucleus is, therefore, the control room of the cell.
