Question

Quizplus · Accepted Answer

Fred Griffith's experiment demonstrated that harmless bacteria can become transformed into disease-causing bacteria by a transformation factor, which is now understood to be DNA. This discovery was a critical step in understanding the role of DNA as the genetic material and has had a significant impact on the field of genetics and molecular biology.
