In cell fractionation various components of cells including its organelles can be isolated in different layers depending upon?
- A
Their physical properties like size & weight
- B
Their physical properties like density
- C
Their electrical properties like their charges
- D
Both a and b
Cell fractionation involves two steps: homogenisation (cells are broken apart in a blender) and centrifugation (cell components are spun in a centrifuge and separated on the basis of density - physical properties of the cell components.
In density gradient centrifugation, the centrifuge tube is filled with a series of solutions of decreasing density - physical properties of the medium.
Cell fractionation involves two steps: homogenization (cells are broken apart in a blender) and centrifugation (cell components are spun in a centrifuge and separated based on their density and physical properties). The various cellular parts separate into different layers depending on their size, weight, and density of the medium. Option A is partially correct because it lists only one parameter however, both a and b options are correct.
Cell fractionation involves two steps: homogenisation (cells are broken apart in a blender) and centrifugation (cell components are spun in a centrifuge and separated on the basis of density and physical properties of the cell components.
Cell fractionation separates organelles based on their size and density, not their electrical charge. Techniques like centrifugation do the separation, while charge is irrelevant here.
