GENERAL HISTOLOGY

Detailed explanation-1: -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. It contains all the information required for the proper functioning of the cell.

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

Detailed explanation-4: -Nuclear pores, small channels that span the nuclear envelope, let substances enter and exit the nucleus. Each pore is lined by a set of proteins, called the nuclear pore complex, that control what molecules can go in or out.
