This video - Exploring Nuclear Organisation: Chromatin, Chromosomes, and the Nucleolus - is the final video in a series of 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
- Understanding the Nuclear Pore: Gatekeeper of the Nucleus
In this video, I explore the organisation within the nucleus, emphasising that it is structured rather than chaotic. I explain how Spectral Karyotyping reveals that chromosomes occupy specific territories and highlights the structured nature of chromatin, which can be either open or closed and influences transcription and replication. I also examine the nucleolus, describing its crucial role in producing ribosomes and signal recognition particles (SRP) and outlining the complex processes of ribosomal RNA (rRNA) synthesis and assembly.
