Answer:
S strain
Explanation:
The Avery experiment demonstrated DNA is the genetic material. It expanded upon the findings made by Griffith.
They used Pneumococcus; Smooth strain which was virulent and the Rough which was not.
Cultures of heat killed smooth strain were prepared after which it was treated with DNases ,RNases and Proteinases to remove DNA, RNA, and proteins respectively. It will then be introduced to living Rough strain.
