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.
