Question

What was the key discovery of the experiments of Avery, MacLeod, and McCarty?

A) Discovery of the structure of DNA
B) Identification of the genetic code
C) Confirmation of DNA replication
D) Demonstration that DNA carries genetic information

Answer 1

The key discovery of the experiments conducted by Avery, MacLeod, and McCarty was that DNA carries genetic information.

Step-by-step explanation:

The key discovery of the experiments conducted by Avery, MacLeod, and McCarty was that DNA carries genetic information. Through their experiments, they found that when DNA was degraded, it was no longer able to transform bacteria, whereas other components such as proteins, carbohydrates, and lipids still retained the transforming ability. This provided confirmatory evidence that DNA, rather than proteins, is the genetic material.
