  • DNALEARNINGCENTER IS SOOOOOOOOOOOOO HELPFUL. I LOVE IT!

  • oh, so that's what they mean by amplified :) Only the desired portion is copied!

  • The DNA is heated, denatured into two separate strands, 15 to 20 nucleotides are present in which they act as primers on the and 5' and 3' end, by doing this there is a middle section. Heat-resistant polymerase (from bacteria from the hot springs) does away with the rest of the dNA strand. The frequency at which a wanted sequence is easy to get by multiple replications. 3/25%, some issues are base pair mismatches or errors.

  • Not as informative as could be, but really beautiful

  • awesome video thank you! perfect for my Biology exam...

  • what is the primer in the PCR? 

  • @isam1335 a synthetic one

  • Had a lot of fun with the comments, ( I'm bilingual too ) - a very nice distraction from learning for biology und biologie =) Anyways, a very good video that helped me a bit more to understand the PCR, even if it was not very detailed. Thank you for that!

  • I wonder how the temperature can go up and down so fast.

  • 3 people couldn't get the concept.

  • ok how do you make the primers, do you add A T G C in a sequenced mix in test tubes and heat treat to cause them to bind into the gene sequence that you want? how do we know that the right genes are being targeted, because at some point the A T G C repeat at different parts along the DNA strand, this process cannot directly find the genes, im guessing its multiple processes after the target strand is found so you take the smaller part and then subdived off of that to get precise gene pieces.

  • This is the best biology video i have ever seen!!!you have more of those??

  • Thank you!!! This visualization helped a great deal for my Biologie homework. :-)

  • @wallacemail you can't even spell biology

  • @zackboomer Sorry, I wrote it the German way! That can happen when your bilingual. So look in a German dictionary and you'll see it's spelt right.

    Don't worry about little things like that. I'm glad though you knew what it meant. Ps. more corrections? If so so's no more time to answer. Ps. so's is short for ...... have a good guess!

  • @wallacemail You are forgiven, Kraut.

  • @zackboomer Thanks Unkraut! You to are forgiven. Just inform yourself better next time before judging, or being Mr/Mrs brainy box! Mein Gott du hast nichts anderes zu tun als nachzuschauen wer was schreibt. Dein Leben muss mega langweilig sein.

    OMG Biologie .....Biology ......ENTSPANNT DICH!!!

  • @wallacemail Sie sind ein Bündel und es nimmt 1 zweites, um auf eine youtube Anmerkung zu antworten. Dieses Argument ist unzulässig. Guter Tag.

  • @zackboomer ???? Never mind! Also Good Day

  • @zackboomer try to translate on your own not via google traslator... you kinda... wrote everything wrong!

  • @MilezJoBroluver94 lol you think I care that I wrote some stupid language wrong?

  • @zackboomer you probably did because you replied. But keep thinking you're a cool dude because you don't care about stupid stuff like languages.

  • @beamoflaser oh, the obvious "you care because you replied" response. I don't give a shit about german because it will never be useful for me.

  • @wallacemail @zackboomer Discussing on the internet is like winning the paraolympics, even if you win, you are still retarded.

  • @ForYeensSake Wow that's a new one. I probably have only heard that one about 4389747239374893 times since I started using the Internet.

  • @zackboomer that was the german word for Biology... Biologie

  • THANK YOU!!!!

  • THANK YOU. YOU JUST SAVED ME.

  • Very good visualization! Gives a good insight of the process! :)

  • where does the primers and polymerase came from?... were they added in the process?

  • @watashiwaka19501

    yeah, before you start the PCR reaction

  • @watashiwaka19501 i know that there are viral cutters and mending chemicals that chop up dna and push it together, because thats the same mechanisms that viruses use to hijack your cells, but from this process i think it has to have more than one PCR step to target more precise gene sequences. great video but i think some more important parts are not shown, yea there is got to be more to this, i wonder what the primers and polymerase steps are called.

  • Shouldn't it be short RNA strands, not DNA strands?

  • Comment removed

  • @zanderez

    No, its DNA strand which is being separated. RNA is usually single stranded. Remember simple rule? DNA is used to make RNA, which in turn, is used to make proteins.
