Transformation is a form of genetic recombination in which a DNA fragment from a dead, degraded bacterium enters a competent recipient bacterium and is exchanged for a piece of DNA of the recipient. In fact, it results from DNA of a bacterial cell penetrating to the host cell and becoming incorporated right into the genotype of the host. “Transformation” may also be used to describe the insertion of new genetic material into nonbacterial cells, including animal and plant cells; however, because “transformation” has a special meaning in relation to animal cells, indicating progression to a cancerous state, the term should be avoided for animal cells when describing introduction of exogenous genetic material. and/or up to 5 antibiotics.

There are clearly instances of lateral transfer, where viruses, for example, carry genes from one species to another or insert themselves in the middle of a gene making substantial changes. NCERT Books. 2. Transformation in bacteria was first observed in 1928 by Frederick Griffith and later (in 1944) examined at the molecular level by Oswald Avery and his colleagues who used the process to demonstrate that DNA was the genetic material of bacteria. Looks like you’ve clipped this slide to already. DNA exchange among bacteriaDNA exchange among bacteria • DNA can be exchanged among bacteria in three ways: 1.
