Synthetic Growth Defect
A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

Need for DNA topoisomerase activity as a swivel for DNA replication for transcription of ribosomal RNA.
Yeast strains with mutations in the genes for DNA topoisomerases I and II have been identified previously in both Saccharomyces cerevisiae and Schizosaccharomyces pombe. The topoisomerase II mutants (top2) are conditional-lethal temperature-sensitive (ts) mutants. They are defective in the termination of DNA replication and the segregation of daughter chromosomes, but otherwise appear to replicate and transcribe DNA normally. Topoisomerase I ... [more]
