Summary Introduction
To review:
The induction of lac operons by external lactose.
Introduction:
Lactose is a sugar found in milk. It is a disaccharide formed of glucose and galactose. Lactose acts as a great source of energy for organisms. It is

How is the activation of the GAL1 gene prevented in thepresence of galactose and glucose?
During SDS-PAGE, glycoproteins migrate as relatively diffuse bands, whereas nonglycosylated proteins typically migrate as narrow, well-defined bands. Explain the reason for this difference in electrophoretic behavior.
Why do E. coli cells with a defective lacZ gene fail to show galactoside permease activity after the addition of lactose in the absence of glucose?
