Question

Quizplus · Accepted Answer

Avery, MacLeod, and McCarty identified DNA as the transforming principle by showing that it survived treatment with proteases and RNases but was destroyed by DNase. Therefore, the transforming factor was DNA. Heating alone would not have destroyed the DNA, as it is typically more stable than proteins and RNA at high temperatures.
