How griffin's experiment helps in the identification of DNA as the genetic material?
Given the state of knowledge at the time of the Avery, MacLeod,and McCarty experiment, why was it difficult for some scientiststo accept that DNA is the carrier of genetic information?
Discuss the experiments Griffith, Avery and Hershey/Chase did in the early 1920-50s that helped determine DNA was the genetic stuff. What was the “take home” from each?
