This practical follows the horizontal transfer of genes from one bacterial strain to another by conjugation. This is one of three ways in which bacteria can pick up genes within the lifetime of individual cells. Horizontal transfer produces an immediate change in the genetic information available in a cell and therefore can result in an almost immediate change in the characteristics of a bacterial cell – for example, conferring resistance to antibiotics.
