Chromatin replication: TRANSmitting the histone code

Efficient overcoming of the nucleosomal barrier and accurate maintenance of associated histone marks during chromatin replication are essential for normal functioning of the cell. Recent studies revealed new protein factors and histone modifications contributing to overcoming the nucleosomal barrier, and suggested an important role for DNA looping in survival of the original histones during replication. These studies suggest new possible mechanisms for transmitting the histone code to next generations of cells. Journal of Nature and Science (JNSCI), 3(2):e322, 2017
