Geometrically Encoded Positioning of Introns, Intergenic Segments, and Exons in the Human Genome
Advanced Science, EarlyView.This study introduces a new hypothesis: exons, introns, and intergenic segments are non‐random projections of the functional layers of 3D structure of chromatin packing domains. Evidence is presented that this “geometric code” may encode volumetric structure, reconciling epigenetic patterns, correlates with oncogenic mutations, acting as a potential ...
