FUNDAMENTALS OF EPIGENETICSCHAPTER 6
Emerging tools use /dCas9 fused to epigenetic modifiers (e.g., DNMT3A, TET1, p300) to add or remove epigenetic marks at specific loci, offering precision control of gene expression without altering DNA.
Conclusion
Gene regulation is a multi-layered, precisely controlled system that enables life as we know it. While the DNA sequence provides the blueprint, the epigenome serves as the instruction manual, marking which pages to read, when, and how often. Understanding this complex interplay is critical for decoding development, disease, and the future of personalized medicine.
