WebKey points: In transformation, a bacterium takes up a piece of DNA floating in its environment. In transduction, DNA is accidentally moved from one bacterium to another by a virus. In conjugation, DNA is transferred between bacteria through a tube between cells. Transposable elements are chunks of DNA that "jump" from one place to another. WebAdd 1μg of plasmid DNA to the medium, and mix. For a 3:1 ViaFect™ Transfection Reagent:DNA ratio, add 3μl of ViaFect™ Transfection Reagent, and mix immediately. Incubate the ViaFect™ Transfection Reagent:DNA mixture for 5–20 minutes at room temperature. Optional: Add mixture to cells without an incubation period.
