CHAPTER 13 Frontiers of Genetics
... Many bacteria contain plasmids, which are small, circular DNA molecules that are separate from the much larger bacterial chromosome. Biologists use plasmids to move genes into bacteria. A restriction enzyme "cuts" a DNA molecule into fragments at specific points. Another enzyme "pastes" a fragment c ...
