Here are some of the main components of a nucleus:
1)Nuclear envelope - The nuclear envelope also known as the the nuclear membrane, surrounds the nucleus and separates the nucleic material from the cell cytoplasm. The nuclear membrane is made up of an outer and an inner membrane that are separated from each other.
2)Nuclear pore: the nuclear membrane has channels through which small molecules can pass through. The pores are made up of proteins and for this reason they are referred to as necleoporins. The nuclear pores allow selective movement of small molecules while disallowing the movement of large molecules such as nuclear material in and out of the nucleus.
3)Nucleolus: the dense mass in the nucleus that serves to synthesize rRNA and assembly of ribosomes.
4)Nucleoplasm: is the protoplasm within a nucleus surrounded by the nuclear membrane. It has nuclear material and nuclear enzymes dissolved in it.
5)Chromatin: are DNA materials that forms chromosomes complexes with other nuclear proteins.
