Question

Pure fractions of cellular components can be isolated by

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

Answer 1

The correct option is D Differential centrifugation

Cellular components can be isolated through differential centrifugation technique because various sub-cellular components differ in their specific gravities. Chromatographic techniques are used for separation of a mixture into its constituents. Microscopy techniques can reveal structural details of cells while autoradiography can be used to study cellular metabolism. X ray diffraction can be used to study the structural details about a crystal of biomolecules through X rays diffraction pattern.
