Define transformation in Griffith's experiment. Discuss how it helps in the identification of DNA as the genetic material.
In Griffith’s experiment, transformation can be defined as a change in the genetic constitution of an organism by picking out up DNA from the environment by the dead organism.
Transformation helps in identification of DNA as in the form of genetic material. When heat was used to kill the virulent bacteria then the bacteria died but their genetic material (DNA) was there. This DNA when took up by the non- virulent bacteria, made them capable of causing harmful infection. Since, ability to cause infection could be passed on by these organisms to their offspring, conclusion was found that DNA was the material that was inherited.
