Chapter 17, Problem 8P

Summary Introduction

To determine:

Whether the gene GAL4 or GAL80 genes can be considered as potential candidates for isolation of mutations that allow the constitutive expression of the target genes along with the characteristic of protein that disrupts the mutation.

Introduction:

Yeast genes have cis-acting elements upstream of their promoters and are similar to enhancers, which are called upstream activating sequences (UASs). UAS_G regulates the several target genes involved in the galactose utilization.
