Question

Isopycnic or equal density centrifugation is achieved in

• A. Buoyant density centrifugation
• B. Density gradient centrifugation
• C. Electrophoresis
• D. Differential centrifugation

Answer 1

Answer: (B)

Density gradient centrifugation

B. Density gradient centrifugation

Solution : Density gradient centrifugation is done to separate molecules based on their similar densities. They are concentrated at different levels during centrifugation based on the densities.This method of separation is independent of time, and relies solely on the actual buoyant density of the particle.

So the correct answer is "Density gradient centrifugation"
