The main reason of this process is to kill off or eliminate bacteria that have failed to take in the plasmid, due to their possession of recombinant DNA plasmid pARA-R (an ampicillin resistance gene), that allows them to survive.

However, after completion of the aforementioned procedure, the bacteria that have been transformed will be able to take in the plasmid.
