    That is why it is MIT ! professors not just teach , they also inspire and make you feel interested , that is what matters , you can have a thousands books to learn the materials , but where you discover the passion? Thanks MIT for these free materials

      i've seen others from MIT courseware, lectures by people who literally have nobel prizes, and they are some of the most boring lectures i've ever seen - I couldn't even get through them. Eric Lander is an amazing lecturer though.

    Just one thing: Rosalind Franklin didn't show her photos of DNA's crystal structure to Watson and Crick. Wilkins showed the pictures to the two men without her permission, and her role in discovering DNA's structure wasn't really acknowledged until a while after she died.

      Exactly! And this happened because she was a woman. The years showed that people like Watson, despite his brilliant work on DNA, are a shame to science. In my classes I always bring the name of Rosalynd Franklin as one of the real key minds behind the discovery.

    • @matthewbartsh9167
      @matthewbartsh9167 2 ปีที่แล้ว

      That part seemed to me to make no sense. Who cares whether the bases only differ slightly. Any difference is enough to encode information. Boringness shouldn't come into it, I would have thought. What bearing does that have on whether it is the "transforming principle"?
      Does he mean those scientists were subpar? If so, why not let us know that? I wish Lander had explained what he meant.
      Edit: Also, so what if (a strange conclusion) "DNA has to be structural, given that it is boring" (or words to that effect)? Even if it were structural it could *also* carry heredity information, just as a load-bearing wall can have writing on it, or could encode information in different color bricks". So Lander seems to be attributing to those WW2 scientists a very strange and absurd line of reasoning.

  • @salvadorhirth1641
    @salvadorhirth1641 4 ปีที่แล้ว

    What a superb lecture, Professor! I'd like to share a hypothesis for the mechanism of huntington's disease: I believe that the inadvertent methylation of the carbon 5, followed by spontaneous deamination of cytosines in CAGCAG triplet repeats form one or more stop codons TAG and when a certain threshold of the formation of stop codons exceeds the DNA glycosylases capacity to repair errors, truncated proteins will be produced and possibly causing the formation of peptides that could interfere with the nuclear pore complexes so that the truncated proteins would get stuck across and in the vicinity of the nuclear membrane; the same transformation of cytosines into thymines in CGA triplet repeats could produce stop codons in the neurons of Parkinson's patients; maybe this phenomenon is the primordial cause of other neurodegenerative diseases; do you think that ( provided my suppositions are correct) DNA methyltransferase inhibitors, like azacytidine and decitabine, could delay the onset of such diseases?

    1st: I could listen to Mr/Dr Landen 4ver!!!😃 So inspiring, so clear; I find myself feeling carried away, humbled, and absolutely jaw dropped by the level of clarity, and this genuine, positive approach, that brings a fresh breeze in every lesson that I watched. Simply fantastic.
    2nd, I can't still wrap my head around the fact that Franklin's image of the DNA molecule was key to deciphering its structure, but then only the two guys received the 1962 Nobel Prize for their work. I am beginning to wonder whether winning the Nobel Prize in any scientific field is still really relevant, considering how much research they miss out from non-white and non- predominantly male labs around the world.
    I'm starting to feel quite depressed about it... IDK. I hope I will be able contribute to change this someday. (We got to do something about it, any ideas you geniuses out there?)

    Feet up feet down assay is about showing a difference on a macro scale of some obvious change ... in this case dead or alive ... active lethal virus will kill while a non-lethal one wont kill ... ie the animal (rat) is either alive (feet down on the ground going about its life) or Feet up (dead no movement)
    Could this type of experimentation be used on a cell that has mutated (ie cancer) and find a way to see HOW it has mutated when compared to a healthy cell of similar or identical function?
