What Are the Major Functions and Structures of a Cell Nucleus?

Structure of Nucleus

 Chemically they are composed of nucleic acid, RNA, and protein. Physically, they are composed of the following components:

• Nuclear membrane: The nuclear membrane is the double-layered transparent membrane that forms the nucleus's outer covering. The outer membrane is permeable, but the inner membrane is not.
• Nucleoplasm:  It is a clear and dense fluid surrounded by a nuclear membrane. It contains a nucleolus and chromosomes.
• Nucleolus: The nucleolus is the denser, smaller, rounder body found in the nucleus.
• Chromosome: A chromosome contains several genes, and these genes are responsible for expressing the characteristics of various species.

Functions of the different parts of a Nucleus

• The primary function of the nuclear membrane is to keep the nucleoplasm, chromosomes, and nucleus separate from the cytoplasm. This membrane is also used to transport internal materials and cytoplasm.
• Nucleoplasm stores chromosomes and performs various organic functions.
• Nucleolus synthesizes and stores various types of RNA and protein.
• The chromosome contains and transmits the organism's hereditary properties.
