Vedclass · Answer

(D) Normal $E. coli$ cells do not naturally possess antibiotic resistance genes such as $amp^R$ (ampicillin resistance),$tet^R$ (tetracycline resistance),or $kan^R$ (kanamycin resistance).These genes are typically introduced into $E. coli$ via cloning vectors (like $pBR322$) during genetic engineering processes to act as selectable markers.Therefore,none of these genes are present in the wild-type or normal $E. coli$ genome.
