Mechanisms of Bacterial Genetic Recombination Genetic Transfer Genetic transfer is the mechanism by which DNA is transferred from a donar to a recipient. In bacteria genetic transfer can happen three ways: Transformation Transduction Conjugation A recombination event must occur after transfer in order that the change in the genome be heritable (passed on to the next generation). Transformation After death or cell lyses, some bacteria release their DNA into the environment. Other bacteria, generally of the same species, can come into contact with these fragments, take them up and incorporate them into their DNA by recombination. This method of transfer is the process of transformation. Any DNA that is not integrated into the chromosome will be degraded.
