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: -Nucleus. The nucleus serves as the cell’s command center, sending directions to the cell to grow, mature, divide, or die. It also houses DNA (deoxyribonucleic acid), the cell’s hereditary material.

Detailed explanation-3: -What does DNA do? DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

Detailed explanation-4: -The nucleus is generally considered the control centre of the cell because it stores all of the genetic instructions for manufacturing proteins. Interestingly, some cells in the body, such as muscle cells, contain more than one nucleus (Figure 2.8. 2), which is known as multinucleated.

Detailed explanation-5: -The Nucleus The nucleus is the control center of the cell. The nucleus contains nearly all of the DNA in the cell and, with it, the coded instructions for making proteins and other important molecules. In prokaryotic cells, there is no nucleus, and the DNA is found in the cytoplasm.
