DNA, RNA, & Protein Synthesis Review LHS

Which bacteria killed the mice in Griffith’s transformation experiment?

• live, harmless bacteria and heat-killed, harmful bacteria

• live, harmless bacteria and heat-killed, harmless bacteria

• live, harmful bacteria and heat-killed, harmless bacteria

• live harmless bacteria, and live, harmful bacteria

Griffith called the process he observed transformation because

• the mouse had been transformed.

• the harmful bacteria had been transformed.

• the harmless bacteria had been transformed.

• the experiment had been transformed.

What did Avery conclude caused transformation?

• DNA was the transforming factor.

• A protein was the transforming factor.

• A carbohydrate was the transforming factor.

• A lipid was the transforming factor.

What property of DNA does bacterial transformation illustrate?

• Bacterial DNA cannot move into other bacteria and function.

• Bacterial DNA can move into another bacteria and function.

• Bacterial DNA uses four nucleotides bases that work in pairs.

• Bacterial DNA is found in a circular chromosome.

Griffith’s experiments advanced the study of genetics by proving that

• there is a chemical that contains genetic information that can be passed from one organism to another.

• bacteria can make people sick by infecting them with a chemical that contains genetic information.

• the bacteria that can make mice sick are the same bacteria that can be grown in culture dishes in a laboratory.

• genetic information can be passed from parents to their offspring during sexual reproduction.

What is inside a bacteriophage?

• protein

• nucleic acid

• lipid

• carbohydrate

What do bacteriophages infect?

• mice.

• humans.

• viruses.

• bacteria.

Why did Hershey and Chase label the viral DNA with radioactive phosphorous and not radioactive sulfur?

• DNA contains phosphorus and no sulfur.

• Proteins contain phosphorus and no sulfur.

• DNA contains sulfur and little phosphorous.

• Proteins acids contain sulfur and little phosphorous.

Which part of the bacteriophage in Figure 12–1 contains genetic material?
