    A 3D Map of the Human Genome

    The human genome is two meters long but fits inside the microscopic nucleus of a cell. The genome also modulates the function of each cell so that the cells operate differently. What makes this happen? Suhas Rao and Miriam Huntley of the Aiden Lab describe a 3D map of the human genome at kilobase resolution, revealing the principles of chromatin looping.

    How Does DNA Fold? The Loop Extrusion Model

    The human genome is two meters long, but it fits inside the microscopic nucleus of a cell. How is this possible? Research conducted in the Aiden Lab at Baylor College of Medicine suggests that the genome achieves this feat by forming loops and domains through a process called extrusion.
