Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the 20-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics.

Just 45 years ago, the age of gene modification was born. Researchers could create glow-in-the-dark mice, farmyard animals producing drugs in their milk, and vitamin-enhanced rice that could prevent half a million people going blind every year. But now GM is rapidly being supplanted by a new system called CRISPR or "gene editing". Using this approach, scientists can manipulate the genes of almost any organism with a degree of precision, ease and speed that we could only dream of ten years ago.

For decades after the identification of the structure of DNA, scientists focused only on genes, the regions of the genome that contain codes for the production of proteins. Other regions that make up 98 percent of the human genome were dismissed as "junk," sequences that serve no purpose. But researchers have recently discovered variations and modulations in this junk DNA that are involved with a number of intractable diseases. Junk DNA can play vital and unanticipated roles in the control of gene expression, from fine-tuning individual genes to switching off entire chromosomes.

For decades after the structure of DNA was identified, scientists focused purely on genes, the regions of the genome that contain codes for the production of proteins. Other regions - 98 percent of the human genome - were dismissed as ‘junk’. But in recent years researchers have discovered that variations in this ‘junk’ DNA underlie many previously intractable diseases, and they can now generate new approaches to tackling them.
