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.
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.
How did Oswald Avery die?
Oswald Avery was diagnosed with liver cancer in 1954. He died on February 20th, 1955 from liver cancer. He was 77.
What was the conclusion from Avery's experiments?
Avery's experiments on bacteria showed that DNA is the genetic material responsible for transformation. This conclusion was a key discovery in the field of molecular biology and laid the foundation for further research on DNA's role in heredity.
Who discovered transformation was by DNA?
The discovery that transformation was mediated by DNA was made by Oswald Avery, Colin MacLeod, and Maclyn McCarty in 1944 with their experiments on pneumococcus bacteria. They showed that DNA was the substance responsible for genetic transformation, contradicting the previously held belief that proteins were the carriers of genetic information.
What did Avery conclude cause transformation?
Avery concluded that DNA is the molecule that changed bacteria.
Did Avery and his colleagues think that the molecule required a transformation might also be a molecule of the gene?
Yes, Avery and his colleagues believed that the molecule responsible for the transfer of genetic information in their experiments with pneumonia-causing bacteria (the transforming principle) could be the molecule of the gene. They identified DNA as the molecule responsible for genetic transformation.
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.
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.
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.
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 was Avery and his group determined which molecule was most important for transformation?

What was the variable in Oswald Avery's experiment?
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.
What was the experimental variable Avery used when he repeated Griffith's work?
Avery used enzymes to break down different components of the heat-killed virulent bacteria to determine which component was responsible for transforming the non-virulent bacteria. This allowed him to identify DNA as the genetic material responsible for the 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?

How did Oswald Avery die?
Oswald Avery was diagnosed with liver cancer in 1954. He died on February 20th, 1955 from liver cancer. He was 77.
