ANATOMY

Detailed explanation-1: -The nucleus is the largest and most significant living organelle of the cell. All cell activities of the cell are regulated by the nucleus. Hence it is called brain or control centre of the cell.

Detailed explanation-2: -A large oval structure called the nucleus (NOO klee us) acts as a cell’s control center, directing all of the cell’s activities. The nucleus is the largest of the cell’s organelles.

Detailed explanation-3: -Nuclei contain the genetic material called DNA that is responsible for controlling and directing all cell activities.

Detailed explanation-4: -The nucleus is like the remote control center of the cell. It acts as the cell’s brain by telling it what to do, how to grow, and when to reproduce. The nucleus is home to the cell’s genes. A membrane, a thin layer that allows chemicals to pass in and out to the rest of the cell, surrounds the nucleus.

Detailed explanation-5: -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.
