Detailed explanation-1: -The nuclear pore is a protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope.

Detailed explanation-2: -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.

Detailed explanation-3: -The nuclear membrane encloses the DNA within the nucleus and protects it from the substances in the cytoplasm. It also regulates the entry and exit of substances in the nucleus.

Detailed explanation-4: -The nuclear envelope protects the cell’s genetic material from the chemical reactions that take place outside the nucleus. It also contains many proteins that are used in organizing DNA and regulating genes.
