Avery and his colleagues wanted to isolate the active chemical responsible for the transformation principle (genes) and group it into a known group of chemicals (proteins, nucleic acids, lipids, polysaccharides...) or at least find out its basic chemical properties. So it could maybe be formulated as follows: "What is the active chemical inducing transformation of Pneumococci Type II to Pneumococci Type III in previously outlined experiments?" Therefore, the null-hypothesis would be: "Which chemical substances can be excluded from being responsible for inducing this transformation?"
HE combined his findings with that of other prominent researchers like Frederick Griffith.
Avery and his colleagues made an extract, or juice, from the heat-killed bacteria. They then carefully treated the extract with enzymes that destroyed proteins, lipids, carbohydrates, and other molecules, including the RNA. Transformation still occurred. Obviously, since these molecules had been destroyed, they were not responsible for the transformation. Your welcome:)

Avery and his group created an extract from bacteria that had been killed by heat and then used enzymes to destroy RNA, carbohydrates, lipids, proteins and other such molecules. Because transformation still occurred, they were able to isolate the molecules vital to the process.
