Answer:
Cesium chloride density gradient centrifugation
Explanation:
Centrifugation is a technique that separates the one type of molecules from the others based on some physical properties such as density, shape, molecular weight, etc.
Meselson and Franklin Stahl grew the E coli cells in the N-14 and N-15 medium. They isolated the DNA from E coli cells and separated the double helices by centrifugation in a cesium chloride density gradient.
The technique of density gradient centrifugation separates the heavy-heavy, light-light, and heavy-light DNA double helices into distinct bands as they differ from each other with respect to density.
