Answer:
allows for selection of E. coli mutants that successfully picked up the plasmid
Explanation:
Ampicillin is a penicilin type medicine or antibiotic that can treat the infections caused by bacteria.
In bacterial transformation lab, the ampicillin is added in the agar in order to select the E.coli mutants which picked the plasmid and have gained ampicillin resistance gene. Bu doing so, it causes the production of the enzymes that prevents the activity of the ampicillin as well as the bacteria survive. The ampicillin antibiotics present in the agar kills the bacteria without having the ampicillin resistance gene.
