Detailed explanation-1: -The nucleus is the largest organelle in the cell and contains most of the cell’s genetic information (mitochondria also contain DNA, called mitochondrial DNA, but it makes up just a small percentage of the cell’s overall DNA content).
Detailed explanation-2: -Nucleus controls all the activities of a cell as it contains the genetic material. nucleoplasm and nucleolus. It controls all the activities of the cell by synthesizing rRNA and releasing into the cytoplasm for protein synthesis.
Detailed explanation-3: -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-4: -The nucleus is the site where DNA is replicated, and DNA is transcribed to make messenger RNA (mRNA) signals to start the process of translation or protein synthesis which occurs in ribosomes in the cell cytoplasm (all the cell body except the nucleus).
