Hello. 1.Why is the kas heading to the place where the guide rnc has settled? And why does the guide RNA attach itself to a specific nucleotide sequence, how does it find them? 2. How does a bacterium understand that macrophage dna has been launched into it? And how does it start to produce those RNAs with the same nucleotide sequence that are contained in the DNA of macrophages? 3. I cannot understand. Does the Cas 9 protein break hydrogen bonds between nucleotides, or does it completely rip the gene out of the DNA molecule? 4. Will the required template be inserted into the DNA molecule by itself, you just need to inject it into the blood plasma, and it will itself get into the part that was removed by the cas-9 protein? 5. Please show the video footage that was filmed in the laboratories. What exactly happens in the nuclei of cells, how does this protein cas-9 carry out its task. Ato with this computer graphics absolutely nothing is clear.

+Bozeman Science, Only a matter of time because some people super mutate into things that eat itself alive like people who were subjected to directly radiation after a nuclear event. The pain levels could be beyond anything that has ever existed in life before. Some scientist and other people could get docs that create a new form of disease that could never ever be fixed or people would discover new ways to fix the "beach" but this is after people become collateral damage in the process. It would seem only people who want to be familiar with such new technology will be the potential victims. Better than chemo maybe but could be a lot worse. It will be a lot interesting to watch on the news from an observation point of view but being within the circle of testers, it could spread into skin like ebola then probably would be a secret quaranteen to probably an MH370 quiet style execution where no one in the world must know or else mass pandemonium for the common good like when they jacked the the software from China having it. They probably jacked the engineers and killed everyone else. They prob have the highest top level top secret people who know the word could never get out and why. I feel as the the technology was so good that if the tech was sold to rogue nations like NK we would all be fucked so action had to be taken to ensure it's kept in the right hands.

@subwayvesubscriber 6 лет назад

Anthony Abelardo You make the education system sound so simple. Sure, there's a well-made 7 minute video about CRISPR on RU-vid, but will you find everything that is taught in school from grade 1 up until graduation? I highly doubt it. Most students need teachers to clarify and explain things they perhaps didn't understand the first or even the second time. They need feedback, criticism, an environment where they can learn to compete and work together. And there are all the social aspects that going to school incorporates. I frankly think many of these things are incredibly valuable and not replaceable by a few succinct videos. And for me personally, videos like this have only served to refresh my memory on topics I have already learned to just get back into it again if I haven't looked at them a while, not completely teach me everything from zero.

@antdx316 6 лет назад

+subwayvesubscriber, They should just show some of these videos in high school so people can decide if they want to learn further rather than have a lot of people waste time and money in a program they won't even get a career they went to college for but then there would be too many people who would be good at what they do and the really best people would have a hard time shining as bright as w/ the way the system is engineered now.

@dmflyboy2 7 лет назад

MINOR quibbles: 1) usually new spacer-repeats are added at the proximal, not distal, end of the CRISPR locus; 2) This is NOT "exactly" how mammalian immune systems work ("just on a larger scale") as you've stated; 3) HOST DNA, not RNA, is used in gene replacement. Nice graphics!

Big thanks and a happy new year!!!

@sdpy15 7 лет назад

Fantastic! I just wanted to point out a mistake: when CAS1 inserts a spacer into the host DNA it is added UPSTREAM (ie: closer to the CAS gene), not downstream. This is due to a "polar" acquisition leading to a sequential "hierarchy". Otherwise great video, you continue to be my fall-back resource for exam preps. :)

So I've just watched half a dozen videos on CRISPR, including this one, and none of them explain how the system can enter every singe cell in a living organism. All the videos (including this one) only explain it once you get the CRISPR/CAS9 into a single cell. How do you get it into a single cell to begin with? And how do you get it into EVERY SINGLE CELL inside a living organism? Can someone explain this? Thanks.

@juliettedaze 7 лет назад

well, i'm a student that just worked on gene editing using crispr and basically, we added plasmid that contained Cas9 and CRISPR to the cells we worked with. We then centrifuged it to break cell walls to allow the plasmid to actually reach the cell's DNA. I hope this kind of helped.

@Mdmathemovie2016 7 лет назад

Thanks for your response. I'm even more confused now, though. If you have to centrifuge the cells and break the cell walls, how do you get CRISPR into living, multi-celled organisms, like a human being. Supposedly there are human studies underway. I don't understand how the system can get into all the cells in a living, human body.

@JPSIBZ 7 лет назад

No one knows for sure yet. There have been varying degrees of success with several different methods. Most notably is the direct injection of a viral vector carrying the crispr/cas 9 genetic code and after transduction, allowing the host cell machinery to assemble the proteins/enzymes themselves. www.sciencedirect.com/science/article/pii/S1931524415003321
