Practice: MalT Mutant
Predict the phenotype of a malT mutant in which malT can no longer bind to the operator:
A) The mal genes would be expressed efficiently only in the absence of maltose
B) The mal genes would be expressed efficiently only in the presence of maltose
C) The mal genes may be expressed continuously
D) The mal genes may never be expressed efficiently
E) Glucose replaces maltose as the regulatory molecule

Practice: Determining Type of Regulation
You are doing an experiment to determine the mechanism of gene expression of a bacterial operon responsible for the utilization of trehalose. You know Bcd1 is the regulator. You have two strains of the bacteria: one has the normal Bcd1 regulator (+bcd1), and the other does not (-bcd1). You obtain the following results when growing the two strains with and without trehalose:
Is this system....
Practice: MalT in Mutant Cell
Predict the phenotype if a wild-type malT gene is introduced into the malT mutant cell (MalT can no longer bind the operator)
