0 0 votes Cesium chloride density gradient centrifugation is commonly used for the separation of DNA molecules. The buoyant density, $\rho$ of a double stranded $Cs^+DNA$ is given by the equation $\rho = 1.66 + 0.098X_{G+c}$ where $X_{G+C}$ denotes total number of $G$ and $C$ mole fraction of $G+C$ number of $GC$ repeats ratio of $G+C$ to $A+T$ content Molecular Biology and Genetics: gate2016 molecular-biology-and-genetics dna analytical-techniques + – Milicevic3306 7.9k points answer comment Share Follow 0 reply Please log in or register to add a comment.
