New research shows DNA is organized in 3D before life “switches on.” Using Pico-C, scientists found fruit fly embryos build a precise DNA scaffold prior to Zygotic Genome Activation. This architecture ensures genes activate correctly, preventing developmental issues. Applied to humans, disrupting this 3D structure triggers immune responses, linking early genome organization to health and disease, highlighting DNA’s pre-programmed order from the start of life.
