Answer:
E) lack antibiotic-resistant genes.
Explanation:
It is plasmid which carries antibiotic-resistant genes in a bacteria so if the bacterium does not have plasmid then antibiotic resistant genes will also be absent in the newly regenerated bacteria.
A plasmid helps in the survival of bacterium by providing defense against various antibiotics.
Bacterial plasmid is a structure which is circular and some plasmids apart from having antibiotic-resistant genes also participate in para-sexual reproduction in bacteria.
