Gene of interest was cloned at site Sal I in pBR $322$. The recombinant plasmid will exhibit susceptibility to
Biotechnology : Principles and Processes
Solution:
It has two antibiotic resistance genes $\left(a m p^{R}\right.$ and tet $\left.^{R}\right)$,
If a gene of interest is cloned at site Sal I in pBR$322$, the so formed recombinant plasmid will exhibit susceptibility to tetracycline only as tetracycline resistant gene gets inactivated due to insertion.
