Bacteria have exhibited colistin resistance in the past, but this time it is different: Previous forms of the resistance weakened the microbes, and the resistance genes were located on DNA that was not easily shared among bacteria.
Answers. Relevance. Rating Newest Oldest. Best Answer: A plasmid is a circle of DNA that bacteria can absorb into the cell. Many times, these new genes may help a bacteria adapt to its surrounding (i.e. the bacteria lives in an acidic environment, the new genes included in a plasmid may help the bacteria adapt to the environment).his is why an entire colony of bacteria may become immune to penicillin. Many scientists take advantage of this by inserting a gene that they want replicated into a plasmid and then inserting it into a bacteria.
