Abstract excerpt
The nature of the DNA damage-induced checkpoint signal that causes the arrest of cells prior to mitosis is unknown. To determine if this signal is transmitted through the cytoplasm or is confined to the nucleus, we created binucleate heterokaryon yeast cells in which one nucleus suffered an unrepairable double-strand break, and the second nucleus was undamaged. In most of these binucleate cells, the damaged...
