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 a membrane-enclosed organelle, found in most eukaryotic cells, which stores the genetic material (DNA). The nucleus is surrounded by a double lipid bilayer, the nuclear envelope, which is embedded with nuclear pores. The nucleolus is inside the nucleus, and is where ribosomes are made.
