• Liquid dish soap

What is the purpose of mushing the strawberries in the Ziploc bag?

• To make them easier to eat

• To break down the cell walls

• To mix them with alcohol

• To remove the seeds

Why is it important to chill the rubbing alcohol before using it in the experiment?

• To make it more effective at dissolving DNA

• To change its color

• To prevent it from mixing with the strawberry solution

• To make it evaporate faster

What role does detergent play in the DNA extraction process?

• It breaks down the cell membrane

• It colors the DNA

• It dissolves the DNA

• It acts as a preservative

Why are strawberries used in this DNA extraction experiment?

• They have a pleasant smell

• They are cheap and readily available

• They contain a large amount of DNA

• They are easy to mash

What happens to the DNA when rubbing alcohol is added to the strawberry mixture?

• It dissolves completely

• It forms a cloudy layer

• It changes color

• It evaporates

How does salt contribute to the DNA extraction process?

• It changes the color of the solution

• It creates an ionic environment for DNA clumping

• It acts as a catalyst

• It dissolves the DNA

What is the main reason DNA is not soluble in rubbing alcohol?

• DNA is too dense

• Rubbing alcohol is too cold

• DNA is polar

• Rubbing alcohol is less dense than the strawberry solution
