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 (from dead organisms).
Transformation helps in identification
of DNA as a genetic material. When heat was used to kill the virulent bacteria,
they died but not their genetic material (DNA). This DNA when picked up by
non-virulent bacteria made them capable of causing infection.
Since, ability (q cause
infection could be passed on by these organisms to their progeny, it was
concluded that DNAwas the material that was inherited.
