Question

Pure fractions of cellular components are isolated by _________.

• A. Chromatography
• B. Differential centrifugation
• C. Scanning electron microscopy
• D. X-ray diffraction

Answer 1

The correct option is B Differential centrifugation

B. Differential centrifugation

Solution : Differential centrifugation is used to separate the components of cell by using a density gradient based on their sedimentation rate during centrifugation. They separate as layers in the solution that with different densities for different cellular component.

So the correct answer is "Differential centrifugation".
