Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the nucleus?
A
The control center of a cell because it contains genetic material called DNA
B
Small molecules
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center. DNA replication, transcription, and RNA processing all take place within the nucleus, with only the final stage of gene expression (translation) localized to the cytoplasm.

Detailed explanation-2: -The nucleus is like the remote control center of the cell. It acts as the cell’s brain by telling it what to do, how to grow, and when to reproduce. The nucleus is home to the cell’s genes.

Detailed explanation-3: -Because nucleus contains a material called gene which controls all activities of cell and its characteristics. Cell nuclei contain most of the cell’s genetic material, organized as multiple long linear DNA molecules in complex with histones, to form chromosomes.

Detailed explanation-4: -Nucleus is known as the control center of the cell as it performs the following functions: The nucleus contains the hereditary material of the cell, the DNA. It sends signals to the cells to grow, mature, divide and die. The nucleus is surrounded by the nuclear envelope that separates the DNA from the rest of the cell.

Detailed explanation-5: -Also, all cells start with nuclear DNA. The reason for this is that DNA contains the basic code that tells each cell how to grow, function, and reproduce.
