Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations.
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.
