What: "They have most of their genes on a chromosome that is passed just to the descendents of each bacterium. But some genes are on a tiny loop of DNA called a plasmid that can leave one bacterium and enter another. If a chromosome is like a hard drive of genetic information, a plasmid is like a flash drive-tiny and portable."
