Question

Disturb the phospholipid bilayer to lyse cells, separate nucleic acids from lipids and proteins, and aggregate or clump nucleic acids. Which substance is most likely used for this process?

a. Isopropanol
b. Sodium acetate
c. Chloroform
d. Ethanol

Answer 1

Chloroform is the substance most likely used to disturb the phospholipid bilayer, separate nucleic acids from lipids and proteins, and aggregate nucleic acids.

Step-by-step explanation:

The substance most likely used to disturb the phospholipid bilayer, separate nucleic acids from lipids and proteins, and aggregate nucleic acids is chloroform (option c). Chloroform is a common solvent used in DNA and RNA extraction procedures. It disrupts cell membranes by breaking apart lipid molecules, allowing for the release of nucleic acids.
