How is a cesium gradient used to separate dna with different densities?
Romashka [77]

Cesium is used in the separation of DNA with different densities. Cesium chloride (CsCl) acts as a density gradient for the separation of the DNA (Deoxy ribonucleic acid), and is used in gradient centrifugation.

CsCl density centrifugation:

  • CaCl solution is kept in the centrifuge tube along with the DNA sample to be separated.
  • The centrifugation causes the solutions to form bands with the denser part at the bottom and the least denser part at the top.
  • The DNA with its density similar to a particular layer of CsCl solution density forms a band in that layer.
