Open in App
Solution
The correct option is A Non-recombinant bacteria containing beta-galactosidase
The blue-white screen is a screening technique that allows for the rapid and convenient detection of recombinant bacteria . This technique is based on the insertional inactivation of the β-galactosidase gene.
Cells transformed with vector containing the recombinant DNA contain an inactive form of the β-galactosidase gene and hence produce white colonies.
cells transformed with non-recombinant plasmid i.e. only the vector, have an active β-galactosidase gene and thus produce blue colonies.
