The variable in Oswald Avery's experiment was the type of enzyme used to break down the polysaccharide capsule in the heat-killed S strain bacteria. By using different enzymes, Avery was able to determine which specific molecule was responsible for transforming the R strain bacteria into the pathogenic S strain.
Oswald Avery tested molecules called DNA, RNA, and proteins in his experiment on the transforming principle in bacteria. He discovered that DNA was the molecule responsible for carrying genetic information and causing hereditary changes in bacteria.
The transforming principle contains DNA molecules. These molecules were identified by scientists Avery, MacLeod, and McCarty in 1944 as the substance responsible for the transfer of genetic information in bacterial cells.
Hershey and Chase's use of radiolabeled bacteriophages demonstrated that DNA, not protein, is the genetic material. This supported Avery's earlier research that implicated DNA as the carrier of genetic information. The radiolabeled phages showed that only the DNA component, not the protein component, entered bacterial cells and played a role in reproduction.
TCH is the chemical in weed that drug tests test for. Luckily for you TCH is stored in fat cells within the body, so the less fat a person is the less time TCH stays in your body. The best way to get TCH out of your system is to work out hard for a couple of days (burning fat) and to drink alot of water (flushes your system). If it makes you feel any better I smoked a lot of weed and then stopped for a drug test. I worked out hard for 8 days straight and drank water until it hurt. I passed the drug test no problem.

DNA. Oswald Avery and his colleagues demonstrated that the transforming agent responsible for the bacterial transformation in Griffith's experiments was DNA, not protein as previously thought. Their work laid the foundation for understanding the role of DNA in heredity.
No, Oswald Avery was not awarded a Nobel Prize during his lifetime. However, his groundbreaking research on the transforming principle of DNA laid the groundwork for future discoveries in genetics and molecular biology.
He showed that DNA is a Transforming factor.
Oswald Avery died on 1955-02-02.

Avery experimented with the transforming principle
American biologist Oswald Avery and his colleagues took Griffith's experiments one step further. To test whether protein was the transforming factor, they treated Griffith's mixture of heat-treated deadly strain and live harmless strain with protein-destroying enzymes. The bacterial colonies grown from the mixture were still transformed. Avery and his colleagues concluded that protein could not be the transforming factor.
