A. X-gal cleaves beta-gal to produce a blue product.

B. X-gal cleaves beta-gal to produce a white product.

C. Beta-gal cleaves X-gal to produce a blue product.

D. Beta-gal cleaves X-gal to produce a white product.

Answer :

Beta-gal cleaves x-gal to produce a blue product. The correct response to the question is option (c).

Define X-Gal.

Galactose and a substituted indole are combined to create the chemical compound known as X-gal. The chemical was produced in 1964 by Jerome Horwitz and associates. The enzyme known as -galactosidase, a glycoside hydrolase, catalyzes the hydrolysis of terminal non-reducing -D-galactose residues in -D-galactosides.

Galactose and 5-bromo-4-chloro-3-hydroxyindole are generated during the breakdown of X-gal by beta-galactosidase. The absence of color in X-gal allows for a test for the existence of an active -galactosidase to be done by checking for blue-colored output.
