Question
10. The gal 1 gene of yeast is induced by galactose. The proper regulation of this gene depends on the gal4 and gal80 genes. For both gal4 and gal80 there are mutant alleles that result in constitutive expression and mutant alleles that result in non-inducible expression.
What pattern of gal1 gene expression would you expect in yeast that contain a constitutive allele of gal4 and a non-inducible allele of gal80? Explain your answer.
