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.
Using plasmids in the lab. Plasmids can be used as vectors to carry foreign DNA into a cell. Once inside the cell, the plasmid is copied by the host cellâs own DNA replication machinery. In the lab, plasmids are specifically designed so that the DNA they contain will be copied by bacteria.sing plasmids in the lab. Plasmids can be used as vectors to carry foreign DNA into a cell.
