Answer: A recombinant DNA is inserted within coding sequence of β galactosidase; this results into activation of the enzyme (called insertional inactivation). It is treated with a chromogenic substance. If the plasmid in the bacteria have an insert blue colour appears, if they do not produce blue colour, they are recombinants.
