Mastering Bio question:
The experimental technique: Density-gradient centrifugation

When a solution of cesium chloride (CsCl) is subjected to high-speed centrifugation, a stable density gradient is formed. Meselson and Stahl found that when cell contents were subjected to centrifugation with a CsCl solution, a band of DNA formed at the CsCl density that matched the density of the DNA. This technique is called density-gradient centrifugation.

The test tubes below show the results of density-gradient centrifugation of five different DNA samples.
Drag the description of each DNA sample to the appropriate location to identify the expected appearance of the DNA band(s) after density-gradient centrifugation.

haha thanks. It wasn't perfect but it did help a little. I had to google a few more images to help get the answer. Our teacher didn't cover this in class - but it's on the homework. so frustrating.

Here is what I got - in case anyone else needs help.
