Which scientist studied bacteria that caused pneumonia that was tested in mice.

• Watson

• Chargaff

• Avery

• Griffith

From his work with mice and pneumonia-causing bacteria, Frederick Griffin found that DNA could be transferred from one organism to another. This is called

• Replication

• Transcription

• Transformation

• Translation

Bacteriophages are

• Viruses that infect bacteria

• Bacteria that infect other bacteria

• Prions that infect bacteria

• Strains of pneumonia that infect bacteria

Hershey-Chase experiment confirms that-

• Protein is genetic material, not DNA.

• Neither protein nor DNA is the genetic material.

• DNA is genetic material,not protein.

• Protein and DNA are genetic material.

What did Avery use to destroy the protein and DNA to prove that DNA was the genetic material?

• Bacteriophages

• X-ray diffraction

• Enzymes

• Radioactive isotopes

What organism did Griffith use?

• pea plants

• fruit flies

• bacteriophages

• mice
