Cloning and mapping of CDC40, a Saccharomyces cerevisiae gene with a role in DNA repair

The cdc40 mutation has been previously shown to be a heat-sensitive cell-division-cycle mutation. At the restrictive temperature, cdc40 cells arrest at the end of DNA replication, but retain sensitivity to hydroxyurea (Kassir and Simchen 1978). The mutation has also been shown to affect commitment to meiotic recombination and its realization. Here we show… CONTINUE READING
