many antibiotics like penicillin act on the bacterial cell wall and break the NAG-NAM bonds, so there is lysis hence death of bacteria, others like tetracyclin stop protein synthesis and so it stops growth, mitomycin and actinomycinD cause breaks in the DNA. So they can act in varied ways but their job is to kill.
