Trans-dominance of dnaA mutants in Escherichia coli

Trans-dominance of dnaA mutants in Escherichia coli

G Zahn et al. Mol Gen Genet. .

Abstract

Temperature sensitivity of growth and DNA synthesis was tested in merogenotes heterozygous for the dnaA allele. All combinations tested (F dnaA+/dnaA5, F dnaA+/dnaA46, F dnaA+/dnaA204, F dnaA5/dnaA+, F dnaA204/dnaA+) were temperature sensitive. The mutant dnaA allele is thus trans-dominant to the wild type allele.
