Nucleic Acid Extraction Quiz

What is the primary purpose of using alcohol precipitation in nucleic acid extraction?

• To heat the solution

• To change the color of the solution

• To remove contaminants from nucleic acid solutions

• To increase the volume of the solution

Which alcohol is primarily used to remove salts during nucleic acid extraction?

• Ethanol

• Propanol

• Butanol

• Methanol

What is the role of isopropanol in the nucleic acid extraction process?

• To color the nucleic acids

• To evaporate the solution

• To precipitate the nucleic acids

• To dissolve the nucleic acids

Why is it important to discard the ethanol wash solution carefully?

• To maintain the temperature of the solution

• To ensure the solution remains clear

• To avoid dislodging the nucleic acid pellet

• To prevent the solution from evaporating

What should be done after removing residual alcohol from the nucleic acid pellet?

• Re-suspend the pellet in nuclease-free water or buffer

• Heat the pellet

• Add more alcohol

• Freeze the pellet
