Bacterial Transformation- definition, principle, steps, examples


Bacterial transformation is a process of horizontal gene transfer by which some bacteria take up foreign genetic material (naked DNA) from the environment. The foreign DNA can be derived from another bacterium that has died and released its DNA, or from a plasmid (a small circular piece of DNA) that has been artificially introduced into the environment. The uptake of foreign DNA can result in changes in the phenotype and genotype of the recipient bacterium, such as acquiring new traits or abilities.
