Inheriting chromosome conformation - Nature Cell Biology
Chromosomes unfold and refold each time cells divide. A study by Schooley et al. demonstrates that chromosome-intrinsic and cytoplasmic factors uniquely contribute to interphase chromosome structure, with new possibilities for how gene expression programs are passed from mother cells to daughter cells.
