AP Biology DNA scientists 2018

What did Avery believe is responsible for transformation?

• DNA

• RNA

• Ribosomes

• Mitochondria

What was the purpose of the Avery experiment?

• He wanted to be better than Griffith

• He wanted to test if RNA was the transforming principle

• He wanted to test if DNA was the transforming principle

• It was an accident

What was the DNA in the virus?

• G. Strain

• S. Strain

• Genetic material

• R. Strain

What are bacteriophages

• Viruses

• Carbohydrates

• Protein

• Lysosomes

What macromolecule did Avery NOT test?

• Proteins

• RNA

• DNA

• Lipid

what phenomenon did Avery witness in his experiment?

• Bernoulli’s Principle

• Griffith’s Principle

• The Transforming Principle

• The DNA Principle

What was the transforming Principle

• Transformation of bacteria from one form to another

• Plant cell transforming to an animal cell

• Membrane changing function

• Oxygen transforms to carbon dioxide

How did Avery prove DNA was the transforming agent?

• When DNA was not present no S cells appeared

• When DNA was present no S cells appeared

• When DNA was present a mutation occurred

• DNA was not the transforming agent

In which direction was the transforming agent passed between cells?

• Living bacteria cells —> dead bacteria cells

• Dead bacteria cells —> Living bacteria cells

Why did Griffith want to conduct an experiment between bacteria?

• He was interested in bacteria and wanted to know more about them

• He suspected that bacteria had a way of communicating with each other

• Griffith thought bacteria could be classified differently

• He was assigned to it by a king.
