What else can I help you with?
Avery and his colleagues thought that the molecule required in transformation might also be the molecule of the gene?
This statement refers to Avery's experiment in 1944, where he discovered that DNA is the molecule responsible for carrying genetic information in bacteria. This finding was a crucial step in establishing DNA as the genetic material, leading to further research in molecular biology.
Oswald Avery and his colleagues showed that the transforming agent in Griffith's experiments was?
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.
What did the result of Avery's experiments show about the elements that cause transformation?
Avery's experiments showed that DNA, not protein, was the molecule responsible for the transformation of bacteria. This provided strong evidence that DNA is the genetic material that carries hereditary information.
What did Avery's experiments show that transformation?
Avery's experiments demonstrated that DNA, not protein, is the molecule responsible for transferring genetic information in bacteria. This was a significant finding as it helped confirm the role of DNA as the genetic material.
How did Avery discover that the material responsible for transformation in bacteria ws DNA?
A series of experiments showed that the activity of the material responsible for transformation was stopped by a DNA destroying enzyme. DNA had the instructions for making the capsule in the S. Strain of S. pneumoniae. I hope this helps!!

What did Avery conclude cause transformation?
Avery concluded that DNA is the molecule that changed bacteria.

Briefly describe how Avery and his group determined which molecules was most important for transformation?
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:)
How did Avery and his group determine which molecule was most important for what transformation?
Avery and his group determined which molecule was most important for transformation by selectively destroying different components of heat-killed S strain bacteria and observing which component was necessary to transfer the virulent phenotype to R strain bacteria. They found that the DNA component was responsible for this transformation, leading to the conclusion that DNA was the molecule responsible for genetic information transfer.
What did Avery's experiments add to the knowledge gained from Griffith's experiments?
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.
What did Avery's experiments show that transformation?
Avery's experiments demonstrated that DNA, not protein, is the molecule responsible for transferring genetic information in bacteria. This was a significant finding as it helped confirm the role of DNA as the genetic material.
How was Avery and his group determined which molecule was most important for transformation?
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.
What was the hypothesis in the Avery Macleod and McCarthy DNA experiment?
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?"
Is it true that Griffth discovered transformation in Bacteria?
No, Frederick Griffith did not discover bacterial transformation. It was Oswald Avery, Colin MacLeod, and Maclyn McCarty who demonstrated that DNA is the genetic material responsible for transformation in bacteria in their famous experiment in 1944.
What experiments helped identify the role of DNA?
