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.

a. True
b. False

Manetho

Answer:

True

Explanation:

Messelson and strahl explain the semiconservative existence of DNA replication by using CsCl gradient centrifugation. The hardest would go and rest at the base of the test tube, while the lightest would be at the top, the lightest would find a position between the heavy and the lightest. When the heavy tube is centralized, from a pool of light, bulky and moderate DNA.

This technique is called density-gradient centrifugation. Hence, the given statement is true.
