New Video Posted: Exploring Nuclear Organisation: Chromatin, Chromosomes, and the Nucleolus

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:

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.

If you would like to say thanks for the video, then please feel free to buy me a coffee at
