Detailed explanation-1: -Nuclei contain the genetic material called DNA that is responsible for controlling and directing all cell activities. This is a very important organelle given its vital function.
Detailed explanation-2: -nucleoplasm and nucleolus. It controls all the activities of the cell by synthesizing rRNA and releasing into the cytoplasm for protein synthesis. The rRNA moves into the cytoplasm through the nuclear pore.
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: -Nucleus is the control central of the cell. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell’s genetic material.
