Quantification model of energy of loop structure on biopolymer

June 3 at 10:00 - 10:45, 2020

Dr. Hiroshi Yokota (Postdoctoral Researcher, iTHEMS)

During cell division, the chromatin fiber condenses into a rod-like shape, which is the so-called chromosome. The chromosome is constructed by consecutive chromatin loop structures whose excluded volu...more
