NEET BIOLOGY

Detailed explanation-1: -The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information. Within the nucleus is a smaller structure called the nucleolus, which houses the RNA (ribonucleic acid).

Detailed explanation-2: -The nucleus, formed by a nuclear membrane around a fluid nucleoplasm, is the control center of the cell. Threads of chromatin in the nucleus contain deoxyribonucleic acid (DNA), the genetic material of the cell.

Detailed explanation-3: -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-4: -By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center.
