  • Bacteria - Exchange of genetic information | Britannica.com

    Bacteria - Exchange of genetic information: Bacteria do not have an obligate sexual reproductive stage in their life cycle, but they can be very active in the exchange of genetic information. The genetic information carried in the DNA can be transferred from one cell to another; however, this is not a true exchange, because only one partner receives the new information.
