How do bacteria exchange genetic material

WebDiscover how genetic material is exchanged between bacteria via conjugation and transduction. 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. WebThe DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid. This sits …
