To study the function of the essential cytosolic Hsc70 genes in yeast, researchers constructed a shuttle vector in which a copy of the Hsc70 gene was ligated to the GAL1 promoter. The vector was then introduced into haploid yeast cells in which all four copies of the Hsc70 genes had been disrupted. Following introduction of the vector, you would expect thata. the yeast cells would grow on galactose but not glucose medium.
b. the yeast cells would grow on glucose but not galactose medium.
c. the yeast cells would grow on either glucose or galactose medium.
