Some genes are regulated through a process by which proteins in the cell nucleus, called histones, are chemically modified by small “chemical marks.” New research from Rockefeller University scientists shows that during specific stages of differentiation in mouse embryonic stem cells, crucial marks can be removed by cutting off the end of the histone’s tail.
