Explanation:
Detailed explanation-1: -Oswald Avery, Colin MacLeod, and Maclyn McCarty showed that DNA (not proteins) can transform the properties of cells, clarifying the chemical nature of genes.

Detailed explanation-3: -Even though Avery’s experiments clearly indicated that genetic material is composed of DNA, most scientists at that time continued to suspect that proteins were the genetic material. Most scientists at that time agreed with Avery’s experiments because of their extensive knowledge of DNA.
