THE MOST BEAUTIFUL EXPERIMENT IN BIOLOGY: Meselson & Stahl, The Semi-Conservative Replication of DNA

yourekascience.org/portfolio/t...
In 1958, Matthew Meselson and Frank Stahl published the "most beautiful experiment", where they demonstrated that DNA undergoes semi-conservative replication. In this video, we describe the experiments that lead to this discovery and why understanding how DNA replicates is so important. This video is a complement to Matthew Meselson's iBiology Discovery talk, where Meselson recalls the events that led him to meet Frank Stahl and to plan and execute these experiments.
This video was produced in collaboration with iBiology.
iBiology (www.ibiology.org) is a growing collection of free open-access online videos by scientists about research and discoveries in fields including cell biology, neuroscience, molecular biology, microbiology, ecology, development, and biophysics, and also features short talks on topics such as professional development, careers, policy, and education. iBiology is funded by NSF, NIGMS, and HHMI, and is supported by the ASCB and UCSF.

Actually, everyone gives Watson and Crick all the credit for discoverying DNA Structure buuuuuutttt, Rosalind Franklin was the one to discover this, for she spent so much time using X-Rays in order to figure out the DNA structure, which caused her Cancer. While she was sick battling cancer, two other students researching DNA Structure in the same University( WATSON AND CRICK) sneaked into her Dorm room and stole all her notes AND Published them taking all credit and A Nobel Prize for it But Rosalind Franklin died of cancer before she could take back all recognition of her Research.

Wow I'm German and hadn't unterstand the Meselson and Stahl experiment til yet. I watched 10 german videos about Meselson and Stahl, but only THIS video has show me how it works! I thank you so much!! :)

Y'know, I'm something of a scientist myself.

[@Ibra4Soso]

simple, well explained, easy and clear sound , may Allah bless you for that !

[@kevineholmes9572]

there's 7 minutes of my life I won't get back... I was looking for the outcomes of the expirement, not the fluff.

[@rachellyman468]

this must have taken ages, but I am so grateful for it! it's difficult for me to pay attention to stuff like this, but the drawings made it very entertaining

[@shahirahsofea6261]

i've never ever written a comment on a youtube's video before. but this video totally helped me and it deserves all the recognition it can get. this video was so amazingly clear, fun to watch, understandable and just life saving. thank you so so much, love from Malaysia !

[@christaguevara7582]

As a biology student I found this really helpful. Thank you for posting it!

Tom has a nice face

[@marinaromanova3475]

The only Meselson and Stahl video on KZbin that actually helped me. Two thumbs up!

[@lillylindner8067]

This was amazing because you gave it so much context. My Biology teacher wasn‘t able to explain it in a logical way. 🙆🏻‍♀️

[@lyzabethhadynedwards2482]

This video was so so SO well done. Please continue on!!

[@nadinetaylor2449]

OMG I finally understand what my teachers were talking about! Thank U so much ☺

[@diraaa99]

Brilliant! Was having a hard time understanding my Biology paper but this makes everything so clear! Thank you very much!

[@ryanandida8618]

I have never studied anything bio related before my first bio class in college. I was crazy nervous but these videos have helped me understand much better! Thank you so much !! :)

[@Myron19]

This is the best video on the internet for learning this.

[@danicading1362]

This literally gonna help me on the bio test tomorrow. Thanks

[@gabriellewilliams1048]

this video is super good! definitely helped me understand this experiment A LOT more than i had before.

Whoever disliked the video has a mental problem ...seriously who In the damn world would dislike this amazing creation, it's perfect from the colours to the voice to the explanation .. everything in this video is perfect.. thank you soooo much ❤❤
