This video - Understanding the Nucleus: Structure and Function | Cell Biology Explained - is the first of four videos on the nucleus. The other three are:
- Understanding the Nuclear Envelope: Protecting and Regulating the Nucleus
- Understanding the Nuclear Pore: Gatekeeper of the Nucleus
- Exploring Nuclear Organisation: Chromatin, Chromosomes, and the Nucleolus
The video explains the cell nucleus, highlighting its roughly spherical shape and double membrane structure, which includes an inner and outer membrane with a perinuclear space. It describes the nucleus's contents, such as chromatin for gene transcription and mRNA splicing, and features like nuclear pores for transport and the nuclear lamina for structural support and various cellular functions. Additionally, I note that the outer nuclear membrane and perinuclear space are continuous with the endoplasmic reticulum.
