== == transformation ------------------------------------------------------------------------------------------------------- Transformation is the process in which a bacteria takes in DNA from the environment. Reference: http://en.wikipedia.org/wiki/Transformation_(genetics) By the way, transduction is the process of DNA transfer by the action of a virus (bacteriophages). The other method of DNA exchange between bacteria is called conjugation, which is the transfer of DNA between bacteria by physical contact.
The process is called transformation. In transformation, bacteria take up free DNA from their environment. The DNA can be integrated into the bacterial cell's genome and can lead to genetic diversity within the bacterial population.

The discovery that transformation was mediated by DNA was made by Oswald Avery, Colin MacLeod, and Maclyn McCarty in 1944 with their experiments on pneumococcus bacteria. They showed that DNA was the substance responsible for genetic transformation, contradicting the previously held belief that proteins were the carriers of genetic information.
•A cell takes in DNA from outside the cell. This external DNA becomes part of the cell's DNA
The process of adding foreign DNA to a bacterial cell is called Bacterial Transformation. It is a technique used very frequently in molecular Biology labs.Ê
