Why Is the Coding Sequence of an Enzyme Beta Galactosidase?

β-galactosidase is an enzyme that converts galactose into lactose. ... The coding sequence for the enzyme ​β-galactosidase is preferred over antibiotic resistance genes because recombinants can be easily visualized and the process is less cumbersome.

Why is the coding sequence of an enzyme beta-galactosidase is a preferred selectable marker in comparison to the ones named above?

inserted within the coding sequence of an enzyme, b galactosidase, which results into activation of the enzyme referred as insertional inactivation coding sequence for the enzyme b-galactosidase is preferred over antibiotic resistance genes because recombinants can be easily visualised.

How is the coding sequence of β-galactosidase considered a better marker than the ones identified by you in the diagram?

b The insertion of rDNA into the coding sequence of an enzyme a-galactosidase leads to the inactivation of the enzyme called insertional inactivation. ... Thus coding sequence of a-galactosidase is a better marker.
