  • Meselson and Stahl experiment - This lecture explains about the famous meselson and stahl experiment that explains the mode of DNA replication. Meselson and stahl did the experiment to prove the semiconservative model of DNA replication. The experiment is performed by growing e. Coli bacteria in heavy nitrogen medium and then transfered to the light nitrogen medium to check the incorporation of new light nitrogen to know the model of semiconservative DNA replication.

    I’m a Microbiology Honours student and for this semester I’ve the subjects, Microbial Physiology And Metabolism, Cell Biology and Molecular Biology. And you’ve helped me tremendously in all of three subjects and for that I would want to say a big thank you. You make everything sound so easy and understandable. Thank you for providing such brilliant lectures!
    Good health and happiness to you!🌟

    There's a mistake- after the first round of replication, conservative was ruled out, because conservative replication would not produce an intermediate strand... it would be light or intermediate, never heavy. The second round of testing was needed to distinguish between semiC and disp. models. Then it was discovered that only two gradients ever appeared; the medium and light. Dispersion would have multiple variants present based on its more random nature.

May be I am wrong but Thank you so much sir for this great explanation no one can explain like you to such complex topics Thank you sir🙏🏻
