Question
Biology Question on Cell: the unit of life
Organelles can be separated from cell homogenate through
A
chromatography
B
X-rays diffraction
C
differential centrifugation
D
auto-radiography.
Answer
differential centrifugation
Explanation
Solution
Organelles can be separated from cell homogenate through differential centrifugation. The basic principle involved here is sedimentation of particles in a suspension by centrifugal force. In a centrifuge, the particles sediment at different rates when an accelerating force is subjected. The rate of sedimentation depends upon the size of the particles, its shape and density.
