Detailed explanation-1: -Plasmids can transfer between different bacteria This means that a bacterium can become resistant to multiple antibiotics at once by picking up a single plasmid. They then become multidrug-resistant. Furthermore, genes that influence bacterial virulence are also frequently found on plasmids.
Detailed explanation-2: -The resistance genes are located on plasmids which have the ability to transfer in vitro, and the plasmids in E. coli play an important role in the multiple antibiotic resistance linked transfer.
Detailed explanation-3: -Antibiotic resistance genes are often used as selection markers, which must not be released to the environment upon final product commercialization. For this reason, generation of antibiotic resistance-free vectors is imperative.
Detailed explanation-4: -Final answer: Its DNA is as long as chromosomal DNA is not a correct statement about plasmids. Q.
