In 1953, Watson and Crick proposed a double-helical structure for DNA and suggested that it replicated in a semi-conservative manner. This method of replication was not universally accepted as correct, however. In this talk, Meselson recalls the events that led him to meet Frank Stahl and to plan and execute the now famous experiment proving that DNA does indeed undergo semi-conservative replication.
Speaker biography:
Dr. Meselson has made important contributions to the areas of DNA replication, repair and recombination as well as isolating the first restriction enzyme. Currently, he is Professor of Molecular and Cellular Biology at Harvard University, where his lab studies aging in the model organism bdelloid rotifers. Meselson is also a long-time advocate for the abolition of biological and chemical weapons. He has received many honors, including a Lasker Award in 2004.

wow..... meselson himself explaning how they got it right.... loved the story...
Imagine talking about your own experiment. Bless this king!!!
Can't believe the actual discoverer is talking here!!
I feel so blessed to have an opportunity to hear such fantastic story behind this experiment. Books don't actually tell you these things. Thank you sir and iBiology for this video😇
It was so immensely and immediately soul stirring a talk. Many thanks for the wonderful lecture. Anindita Banerjee, India
!!!!! THANK YOU, iBIOLOGY !!!!!
so Happy and privileged to hear Messelson and Stah's elegant experiment from The Discoverer itself
Thank you very much sir
Your contribution for science is amazing 🙏🏻🙏🏻
Great, Thank you Sir, wonderful experience.
What a great speaker and presenter. Wow
Simply fascinating!
Thank you for your teaching !
Thank you for making this available. I would be happy to translate it into Portuguese for my students, if you could make this possible.
Respect!
beautiful minds, thanks a lot :)
That was BEAUTIFUL
Most Beautiful indeed
Thank you so much. Please can you tell us how the semi conservative model of DNA can explain Taylor experiment?
As I recall (perhaps correctly) Herb Taylor BRIEFLY labeled the DNA of root tip chromosomes and looked at the distribution of label in the next cell generation.The label was transmitted intact into one of the two daughter chromosomes. This lovely experiment, which preceded our experiment with E. coli, was not widely interpreted as support for the Watson-Crick model only because the relationship of DNA to the structure of the chromosome was unknown
Awesome vedio
Please explain immortal strand hypothesis
4:20 Are Jim Watson and James Watson the same person or related in any way?
Yes. They are the same person. Jim is often a nickname for James.
@@alexasawa1932 That's crazy. To think two of the most esteemed researchers in biology were teacher-student!
