Detailed explanation-1: -The nucleus (plural, nuclei) houses the cell’s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins.

Detailed explanation-2: -FIGURE 5: Mitochondria are structures within the cell cytoplasm. The nucleus (Figure 6) 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: -Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.

Detailed explanation-4: -The nucleus is the command centre of the cell, containing the genetic instructions for all the materials a cell will make (and thus all of its functions it can perform). The nucleus is encased within a membrane of two interconnected lipid bilayers, side-by-side.

Detailed explanation-5: -Chromosomes are present in the nucleus, not nucleolus. The nucleus is surrounded by nucleus membrane, s not cell membrane.
