NEET BIOLOGY

Detailed explanation-1: -Nuclei contain the genetic material called DNA that is responsible for controlling and directing all cell activities.

Detailed explanation-2: -Nucleus-The control center of the cell that directs all of the cell activities. Genetic material is contained inside.

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 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. The rRNA moves into the cytoplasm through the nuclear pore.

Detailed explanation-5: -Nucleus: The nucleus is the most important organelle of the cell which controls all the cellular activity. It contains the genetic material in the form of DNA which is protected by the nuclear envelope.
