The colonies of recombinant bacteria appear white in contrast to blue colonies of non-recombinant bacteria because of:
View answer and explanation
Correct option: D
Non-recombinant bacteria containing beta-galactosidase
Option B (Insertional inactivation of alpha-galactosidase in recombinant bacteria) is correct because when a gene is inserted into the LacZ gene, it disrupts the production of functional alpha-galactosidase, leading to white colonies.
