Scientists Reveal Hidden Second Layer of Human DNA

Human DNA. Credit: vediphile / CC BY-SA 4.0 In a major advance in genetics, scientists at Northwestern University have uncovered what researchers describe as a hidden second layer of human DNA. By mapping how the genome folds and shifts inside living cells, the team has revealed how the physical structure of DNA helps control gene activity. The research, conducted with the 4D Nucleome Project and published in Nature, offers a new understanding of how genetic instructions operate beyond the DNA sequence itself. DNA folding shapes gene activity Scientists found that DNA inside the nucleus does not exist as a straight strand. Instead, it folds into loops and forms compartments that...
