How cell identity is preserved when cells divide
A new theoretical model helps explain how epigenetic memories, encoded in chemical modifications of chromatin, are passed from generation to generation. Within each cell’s nucleus, MIT researchers suggest, the 3D folding patterns of its genome determines which parts of the genome will be marked by these chemical modifications.
