Text Solution

Verified by Experts

The correct answer is:

Antibiotic resistance genes are used as selectable markers to distinguish transformed cells.

Insertional inactivation helps identify recombinants when insertion of foreign DNA disrupts a marker gene (e.g., lacZ, tet R ).

Gene cloning is a process of making copies of DNA, not a method for differentiating recombinants and non-recombinants.
