    You cover all the nitty gritty bits that other videos gloss over but that are crucial for comprehension! I finally understand.

    When I find your videos, without fail, you are the one I can trust to fill those tiny gaps of detail to help my understanding. There are many other great efforts on RUclips like this but your videos have added clarity in the drawings and in the voice/ quality. I'm half deaf and I use subtitles which don't even work on most of these highly technical biology videos. I don't even need subtitles with your voice, I can really hear the high frequency consonants which are what piece words together for my deafness type. Thank you for caring and sharing x

    WOW. I have never taken a biochem course and I was able to grasp what you taught in this video.

    Well I sure am glad you didn't scrap this video, even with the mistake (which I realize was a consequence of explaining PCR at the same time, which *would* use two primers for the exponential growth), it was perfectly clear and understandable. Thank you so much! :D

    Can you not have fragments, increasing in length, with termination nucleotides farther upstream of normal dNTPs proceeding the primer (and thus in between the primer and termination nucleotide)? I think I may be missing something, but in other words, how does one make sure the nucleotides in between the termination sites are being covered?
    *My best guess is that the presence of the other ddNTPs along with the other fragments in the other tubes are supposed to obviate the areas not covered by another tube and in effect, “pick up the slack” between tubes to provide full coverage. This question is specifically for the first way.

    Thank you so much, Sir! Your explanations a very helpful! How do you make sure that the dideoxynucteotides attach at every possible location? Just by putting enough of them in the tube and allowing enough time?

    I don't get one thing, if the dna strand is unknown and we want to sequence it, how do we make a primer for it? How do we know what sequence the primer has to be if we don't know its sequence! Can someone explain

    I have one question, I don't get it, how are the bands visualised in the electrophoresis (in the Sanger Method)? Are ddNTP or dNTP labeled some how?
    Thank you! Great video :)

  • @MsTommyknocker

  • @MsTommyknocker
    @MsTommyknocker 10 лет назад

    I don't understand. How many ddNTPs do you put in one test tube?? And how can the polymerase products have varying lengths in single testtube??

    • @federicogermanespinosa4686
      @federicogermanespinosa4686 8 лет назад

      There are different percentages in the mix, and in the case of T for example it´s quantity will be much higher than the normal dNTP.

    How do you ensire that it is not just the 2 ssDNAs that reanneal??

  • @MsTommyknocker
    @MsTommyknocker 9 лет назад

    Why dont the two strands just reanneal??

    If you dont know the sequence then how can you use proper prime?

    • @HardlySimpleFilmsFCX
      @HardlySimpleFilmsFCX 9 лет назад +1

      +lateef lateef my guess is that they use a primer on a sequence commonly known to be in every strand (i.e. the tata box) but I thought the same thing.

  • @gmcenroe
    @gmcenroe 4 года назад

    Don't you need single strand of DNA or just one primer that reacts with one strand of the double stranded DNA, otherwise you are running 2 simultaneous extension reactions? Your diagram shows 2 primers, one for each strand. Your explanation needs some work such as the ratio of ddnucleotide vs normal nucleotide in the chain extension reaction.

    Most people on this planet have heard the term "genie in a bottle" ...this term come about in arab lands where the holy trinity under a grand delusion commanded angels to appear coming out of bottles to trick people and telling them they had three wishes that the genie could grant them ...obviously this is more madness from the holy trinity ...over time stories about the wishes that could be granted and became exaggerated ...there is only so much (a little) that the holy trinity can do. They cannot Create anything of a physical form and can only produce visions that have a solid feeling which feel real to people and some think the vision are Creations when they are not. Only The Creator Of All Particles Can Actually Create.
