The following points highlight the six main components of the nucleus found in cells. The components are: 1. Nuclear Envelope 2. Nuclear Lamina 3. Nucleoplasm (Nuclear Sap) 4. Nucleolus 5. Chromatin Fibres 6. Nuclear Matrix. Component # 1. Nuclear Envelope: The nuclear envelope is made up of two concentric membranes, each of 7-8 nm thickness. The space between the two [...]
The following points highlight the five main structures of nucleus and its functions. The structures are: 1. Nuclear Envelope or Karyotheca 2. Nuclear Lamina 3. Nuclear Matrix 4. Nucleoplasm 5. Nucleolus. Structure # 1. Nuclear Envelope or Karyotheca: The nuclear membrane or karyotheca form an envelope-like structure around the nuclear contents and is commonly known as nuclear envelope. The nuclear [...]
In this article we will discuss about Nucleus on Cell Biology:- 1. Introduction to Nucleus 2. Definition of Nucleus 3. Number 4. Shape and Size. Introduction to Nucleus: The nucleus is an important cell organelle. It is just like the central nervous system of our body. So the nucleus is simply called the brain of the cell or 'controlling centre [...]
