Detailed explanation-1: -The nucleus is the largest organelle in a eukaryotic cell, and it’s considered the cell’s control center. It contains most of the cell’s DNA (which makes up chromosomes), and it is encoded with the genetic instructions for making proteins .

Detailed explanation-2: -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-3: -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-4: -This organelle has two major functions: it stores the cell’s hereditary material, or DNA, and it coordinates the cell’s activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division).
