Matthew Meselson (Harvard): The Semi-Conservative Replication of DNA

www.ibiology.o...
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.

Imagine talking about your own experiment. Bless this king!!!

[@monikajyotikujur2055]

wow..... meselson himself explaning how they got it right.... loved the story...

[@bradleyli1569]

Can't believe the actual discoverer is talking here!!

[@tusharmadke4615]

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😇

[@lawandpramod609]

so Happy and privileged to hear Messelson and Stah's elegant experiment from The Discoverer itself

Thank you for making this available. I would be happy to translate it into Portuguese for my students, if you could make this possible.

[@AmitBiology]

Thank you for your teaching !

[@Yazidart-bm3bm]

Thank you so much. Please can you tell us how the semi conservative model of DNA can explain Taylor experiment?

[@franklinstahl5319]

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

Respect!

4:20 Are Jim Watson and James Watson the same person or related in any way?

[@alexasawa1932]

Yes. They are the same person. Jim is often a nickname for James.

[@virajgorthi7488]

@@alexasawa1932 That's crazy. To think two of the most esteemed researchers in biology were teacher-student!

[@pulikkanjoby5435]

Thrilling

[@leokch2009]

beautiful minds, thanks a lot :)

[@sierrabhatia4966]

That was BEAUTIFUL
