Fig. 5From: Haploid yeast cells undergo a reversible phenotypic switch associated with chromosome II copy numberAn additional copy of his7-1 improves growth of an Isp+ isolate (p3) on histidine dropout medium. Shown are five-fold serial dilutions for representative clones starting from equal number of cells, after 14 days of incubation. Vector, pRS316. his7-1, pRS316-his7-1Back to article page
