Briefly define transformation and describe the relationship between the phenomenon of transformation and the discovery that DNA is the genetic material in bacteria
What will be an ideal response?
Transformation is the process whereby one organism is genetically altered by exposure to DNA from another organism. Because DNA can carry heritable "traits" from one organism to another, it must be the genetic material.
