The colonies of recombinant bacteria appear white in contrast to blue colonies of non-recombinant bacteria because of
-
Non-recombinant bacteria containing β-galactosidease
-
Insertional inactivation of α - galactosidase in recombinant bacteria
-
Insertional inactivation of α-galactosidase in recombinant bacteria
-
Inactivation of glycosidase enzyme in recombinant bacteria
