Molecular analysis of Saccharomyces cerevisiae chromosome I. On the number of genes and the identification of essential genes using temperature-sensitive-lethal mutations.

Abstract excerpt

Previous analyses of Saccharomyces cerevisiae chromosome I have suggested that the majority (greater than 75%) of single-copy essential genes on this chromosome are difficult or impossible to identify using temperature-sensitive (Ts-) lethal mutations. To investigate whether this situation reflects intrinsic difficulties in generating temperature-sensitive proteins or constraints on mutagenesis in yeast, we...
