To investigate the role of DNA polymerase alpha in the checkpoint operating in S-phase we investigated the phenotype of germinating spores that had been disrupted for the pol1 gene by insertion of a single copy of the ura4 gene (Singh and Klar, 1993). Following sporulation of a pol1::ura4+/pol1+ ura ...
