Detailed explanation-1: -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-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. The rRNA moves into the cytoplasm through the nuclear pore.
Detailed explanation-3: -In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
