To Study the Function of the Essential Cytosolic Hsc70 Genes

question 44

Multiple Choice

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 that

• A)the yeast cells would grow on both glucose and galactose media.
• B)the yeast cells would grow on glucose but not galactose medium.
• C)the yeast cells would grow on galactose but not glucose medium.
• D)on transfer to either glucose or galactose medium,the vector-carrying cells would eventually stop growing because of insufficient Hsc70 activity.
