A researcher would like to separate viral DNA from the viral coat proteins using a density gradient.Which material would she use to set the density gradient?

Question

Quizplus · Accepted Answer

Cesium chloride is commonly used to set density gradients for separation of biological molecules as it forms a stable solution with a high density range. The viral DNA and coat proteins can be separated based on their different densities in the gradient. Heavy nitrogen, heavy oxygen, and radioactive carbon are not commonly used for setting density gradients. Sodium chloride is used for salt gradients but is not ideal for separating DNA and proteins based on density.
