The medium used by Meselson & Stahl for confirmation of the semi-conservative method was:
Correct answer: B. Cesium chloride
- A. Calcium chloride
- B. Cesium chloride
- C. Calcium carbide
- D. Silicon carbide
Explanation
Meselson and Stahl used density gradient centrifugation in CsCl with isotopes of nitrogen (¹⁵N and ¹⁴N) to prove semi conservative DNA replication.
