Meselson and Stahl relied on equilibrium density gradient centrifugation in a _______ solution to resolve the DNA containing ¹⁴N from the DNA containing ¹⁵N. A) radiolabelled phosphate B) calcium chloride C) radiolabelled nitrogen D) sodium acetate E) cesium chloride

Question

Quizplus · Accepted Answer

Meselson and Stahl used cesium chloride (CsCl) solution for equilibrium density gradient centrifugation because CsCl forms a density gradient and DNA band can be visualized by staining with ethidium bromide. This allows for separation of the different densities of the DNA containing ¹⁴N from the DNA containing ¹⁵N.
