WebIn 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. WebPlasmid.

DNA replication is fundamental to the propagation of all life on the planet. Remarkably, given the central importance for this process, two distinct core cellular DNA replication machineries have evolved. One is found in the bacterial domain of life and the other is present in Archaea and Eukarya.
