The gene RAD50 was located by the ability of subclones to restore the Rad+ phenotype following transformation of a rad50-1 mutant. Disruption of the gene was achieved by directed integration of a plasmid carrying a fragment internal to RAD50. Haploids with the disrupted gene are viable and do not differ in growth rate or plating efficiency from isogenic rad50-1 or Rad+ strains.
