CsCl gradients separate on the basis of density, so a molecule made up of ribonucleotides has a slightly, but significantly, blank makes a ribonucleotide molecule slightly heavier than a deoxyribonucleotide molecule, while the volumes occupied are blank. \rm CsCl gradients separate on the basis of density, so a molecule made up of ribonucleotides has a slightly, but significantly, blank density than a molecule made up of deoxyribonucleotides. density than a molecule made up of deoxyribonucleotides.

Answer: This process used in carrying out the experiment is known as Density gradient centrifugation where the molecule is being moved from an area of lower concentration to an area of higher concentration.

Explanation:

In a normal circumstances, Under high centrifugal force, a solution of cesium chloride (CsCl) molecules will separate DNA from RNA.The Cesium ions will be forced away from the center towards the outer end of the tube, but will at the same time diffuse back towards the top of the tube, thus forming a shallow density gradient. DNA molecules placed in this gradient will migrate to the point where RNA have the same density as the gradient (the neutral buoyancy). Density gradient centrifugation shows the presence of messenger RNA in cells, which scientists use to determine an essential molecule for converting genetic information in DNA to expressed proteins. Scientists also used it to purify plasmids, circular pieces of bacterial DNA used for genetic engineering.
