What is Nucleus?
The nucleus found in eukaryotes is fully enclosed by a double membrane. The nucleus contains genetic materials which are composed of DNA, RNA, histones & Protein. Gene is transferred from generation to generation. The nucleus functions to control cell growth, regulation, synthesis, and reproduction.
Structure of Nucleus
The structure of nucleus is dicussed below:
Nuclear Envelop
- It is a double membrane structure found in eukaryotic cells surrounding the nucleus and occupies about 10% of cells volume.
- It is composed of a phospholipids bilayer
- Bilayer contains nuclear pores that allow the exchange of biomolecules in and out of the nucleus.
Nucleolus
- Nucleolus is a specialized region within the nucleus containing contains RNA and proteins and is responsible for ribosome biogenesis.
- It is essential for producing rRNA and assembling ribosomal subunits, which are key players in protein synthesis.
- During the synthesis of protein, all components of RNA and Proteins come together to form ribosomes.
Nucleoplasm
- The nucleoplasm form of aqueous substances contains organic and inorganic dissolved materials within the nuclear membrane.
- It is also known as karyoplasm, composition the same as cytoplasm. Protect genetic material by its ionic balance.

Difference Between Nucleus And Nucleoid
Difference Between Nucleus And Nucleoid: Nucleus is a double membrane-enclosed organelle and the nucleoid is present in prokaryotes. Both the nucleus and nucleoid carry the genetic material but there are some major differences between them.
