This video - Understanding the Nuclear Pore: Gatekeeper of the Nucleus - is the third in four videos on the nucleus.
The other three are:
- Understanding the Nucleus: Structure and Function | Cell Biology Explained
- Understanding the Nuclear Envelope: Protecting and Regulating the Nucleus
- Exploring Nuclear Organisation: Chromatin, Chromosomes, and the Nucleolus
In the video, I explore the structure and function of the nuclear envelope and its critical role in maintaining the environment of the nucleus. I explain how the nuclear pore facilitates gated transport, allowing materials to move between the nucleus and the cytosol. Highlighting its complexity, I described how the nuclear pore is composed of numerous nucleoporins, forming a cylindrical channel that selectively regulates the passage of molecules based on their size, with larger molecules requiring active transport mechanisms.
