Abstract. In contrast to cdc 8 and cdc 21, mitochondrial DNA replication continues for a long time at the nonpermissive temperature in five other cell division cycle mutants in which nuclear DNA synthesis ceases within one cell cycle: cdc 4, cdc 7, and cdc 28, which are defective in the initiation of nuclear DNA synthesis, and cdc 14 and cdc 23, which are defective in nuclear division. NUMTs and the cell's mitochondrial DNA concentration have been implicated in promoting nuclear DNA replication in S. cerevisiae (Blank et al., 2008, Chatre and Ricchetti, 2011).
