Oswald Avery's Experiments and Discoveries

What was Oswald Avery's main objective in his experiments?

• To demonstrate that carbohydrates are involved in bacterial transformation

• To show that lipids are the key to bacterial transformation

• To prove that proteins are the cause of bacterial transformation

• To identify the specific macromolecule responsible for bacterial transformation

What was the result of Avery's experiment when he broke down proteins?

• The mice became more virulent

• The transformation stopped, confirming proteins were the cause

• The transformation still occurred, ruling out proteins

• The mice survived, indicating proteins were responsible

What conclusion did Avery reach after testing carbohydrates?

• Carbohydrates had no effect on transformation

• Carbohydrates were responsible for transformation

• Carbohydrates increased the virulence of bacteria

• Carbohydrates were the building blocks of DNA

Which macromolecule did Avery identify as responsible for bacterial transformation?

• Carbohydrates

• Proteins

• Lipids

• Nucleic acids

What did Avery's experiments reveal about lipids?

• Lipids had no effect on the transformation process

• Lipids were the building blocks of DNA

• Lipids were the cause of bacterial transformation

• Lipids were more important than nucleic acids
