We performed a directed evolution experiment under the selective stress of an alternative carbon source on a ploidy series of 1N, 2N, and 4N Saccharomyces cerevisiae (S288c:BY4741) strains. The strain
Chromosome I from the yeast Saccharomyces cerevisiae contains a DNA molecule of approximately 231 kbp and is the smallest naturally occurring functional eukaryotic nuclear chromosome so far characteri
