New video posted: Gene Regulation - how do cells control the expression of genes?

I have just posted a video that looks at the complex processes of gene regulation and protein production within cells. In the video, I explore six key stages where cells regulate protein synthesis, ensuring precise protein production according to cellular needs. These stages include:

  1. Transcriptional Control: The initiation of RNA production and the involvement of transcription factors.
  2. RNA Processing: The conversion of pre-messenger RNA to mature mRNA, including splicing and editing.
  3. Transport and Localisation: The transportation of mRNA to the correct cellular locations for protein synthesis.
  4. Translational Control: Regulation of mRNA translation within the cellular environment.
  5. RNA Degradation: Mechanisms that determine the lifespan of mRNA molecules.
  6. Protein Regulation: Various methods cells use to control protein activity, such as chemical modifications and localisation.
