FAQs on Meselson Stahl Experiment Video Lecture - Biology Class 12 - NEET

1. What is the Meselson Stahl experiment?
Ans. The Meselson Stahl experiment was a groundbreaking experiment conducted in the 1950s by Matthew Meselson and Franklin Stahl. It aimed to determine the mechanism of DNA replication in cells.
2. What were the key findings of the Meselson Stahl experiment?
Ans. The key findings of the Meselson Stahl experiment were that DNA replication occurs in a semi-conservative manner, meaning that each newly synthesized DNA molecule contains one original strand and one newly synthesized strand. This finding supported the Watson-Crick model of DNA replication.
3. How was the Meselson Stahl experiment conducted?
Ans. The Meselson Stahl experiment involved growing bacteria in a medium containing a heavy isotope of nitrogen (15N). After several generations, the bacteria were switched to a medium containing a lighter isotope of nitrogen (14N). DNA samples were then extracted and analyzed using a technique called density gradient centrifugation.
4. What were the implications of the Meselson Stahl experiment?
Ans. The Meselson Stahl experiment provided strong evidence for the semi-conservative model of DNA replication, which is now widely accepted. It also helped further our understanding of how genetic information is passed on from one generation to the next.
5. How did the Meselson Stahl experiment contribute to the field of molecular biology?
Ans. The Meselson Stahl experiment revolutionized our understanding of DNA replication and laid the foundation for further research in molecular biology. It provided crucial evidence for the semi-conservative replication model, which is fundamental to our understanding of genetics and heredity. This experiment also paved the way for subsequent studies on DNA replication in various organisms.
