The scientific legacy of Dolly the sheep

この記事を書いている人 - WRITER -

Twenty years ago, British scientists introduced the world to Dolly the sheep, the first mammal to be cloned using nuclear transfer.

She only lived for seven years, but the scientific advances that came from her creation continue.

Al Jazeera’s Barnaby Phillips reports from London.

    Cloning would be great for infertile men and women to get a child though. So hopefully SOMEONE is trying to figure out how to clone humans safely.

    • Avatar Gilbert Plays ☆ #1 Gaming Channel says:

      one step at a time.

    • Avatar Zlata A says:

      Johan Abdullah Holm why would you clone a child when you could adopt one??

    • Avatar Johan Abdullah Holm says:

      Everyone would adopt if it was easy.

      Adopting is incredibly time consuming, expensive and not all married couples are allowed to adopt due to all sorts of restrictions. Maybe the man is over 40 years old, maybe they have only been married 3 years and so on and so forth. Sometimes people can only adopt if both parents have the correct nationality, cloning is way less restrictive and I would imagine much much cheaper.

    • Avatar I Muted Notifications So Don't Bother Replying says:

      Lmao you would want your kid to be an exact clone of yourself?😂

    • Avatar Jullian Pratt says:

      @Johan Abdullah Holm it’s 100,000$ to clone a dog, but u feel it’s less time consuming and expensive to clone humans than to adopt a child?

      Itt is an human being cloned, therefore it would count as a person, it implies that if not willing to donate them, her choice shall be respected.

      Watch “Never Let Me Go”. Actors are Keira Knightly, Andrew Garfield and Carey Mulligan.

    • Avatar Liam Alistarr says:

      There is research for that but people don’t like that because they don’t like the idea of killing embryos. Scientists idea is that you use this process and then stop the process before the embryo becomes a fetus and then you take the stem cells from the umbilical cord and use those to make organs. As far as I know, this type of research has been ban in the US though.

    The greater question is, can they be patented? can they be owned? In the us, if you change it genetically you can patent it which means you own it at an existential level. That’s a huge can of worm i doubt any of us can fully intellectually decipher, especially with corruption going on in our courts.

    • Avatar Daniyal Ahmed says:

      Also will the cloned human be slave of the patent owning company?

    • Avatar Sara3346 says:

      A clone is by definition unchanged though so I think the answer should be no.

    We should start cloning humans. Next step in technology advancement. What are we waiting for.

      ^ “Then we can put storm trooper costumes on them and re-enact star wars.” – Ali Khan

    • Avatar 7w4c says:

      Ali Khan well there is a slight chance that we could accidentally make a brand new disease with no knowledge about it and no cure which could ravage the world and cause mass hysteria and a global economic breakdown as nations turn to war against other nations for supplies to fend off the disease starting in a new world war which would most likely end in nuclear warfare all because we cloned a human and created a new disease.

    • Avatar C C says:

      Ali Khan because science has always lost the battle with Mother Nature. Look at what’s happened to the earth due to modern farming techniques. We now have no choice but to put chemicals in the soil in order to make it fertile. If human cloning advances the same way farming did, we may have no choice but to put chemicals in to human beings in order to make them fertile.

    i have no doubt in my mind that a human has been cloned in a top secret black operation style experiment.

      Mining Llama they mixed a sheeps dna with a spiders

    • Avatar Seth H says:

      That wouldn’t work because we don’t have the same amount of chromosomes

  17. Avatar Not Aleesha says:

    It seems like they took a sperm from one sheep and an egg from another sheep and just put them together in a third sheep, no? I thought cloning is when you make multiple beings from like synthetically created eggs and sperms (so that they’re all identical)… Just kind of confused about the whole process and how they got these “sisters” to be identical

    • Avatar movie madness says:

      @goodness I’m not a kid. Like I told you I have a degree it biology

    • Avatar goodness says:

      @movie madness Read my comment properly grown up kid.

      @movie madness And a degree holder won’t make silly grammatical errors.

      @goodness ok whatever you say you drunk wife beater

    • Avatar goodness says:

      @movie madness well whatever you assume me to be , I don’t care for I am simply not that . And by the way you are wasting your time and others time as well by making silly, stupid, totally impertinent comments . By the way who cares about people who like you are ignorant no matter what. Like your name says you aren’t mad not only about movies but you are a mad yourself. By the way if you can’t back your claims or defend yourself with reasonable , scientific and logical statements , rather than commenting stupid and silly taunts , just shut up and go on about your work if you have one. Again for heavensake just shut up.

      What? Yes they can with humans, the only thing holding it back is the ethical boundrys. They have as of 2018 cloned monkeys so therefore cloning other primates (Including humans) is difinitely possible.

    Why clone a sheep and not a human?!
    It stupid!
    They both are living creatures!! So why do scientists clone animals but then say no when people ask them to clone a human?!
    We’re not the most important race you know!!!

    . .

    • Avatar lovelyn vigilia says:

      Okay, first of all, that’s already a thing. Second of all, sheep’s are more easier, and (I believe) is cheaper, since nobody is gonna insist to contribute their egg cells from their ovaries (from a woman) and infuse them with cells from another man (which could be a stranger) to create a “clone” human, when she can just do it with her husband.

      And, btw. “Cloning” humans is basically reproducing. A.K.A giving birth to an infant.

    • Avatar lovelyn vigilia says:

      And.. They’re only doing it out of curiosity, to seek greater information for future projects.
      I hope this gave you a better understanding to your question :)!

  41. Avatar Camila Icochea says:

    This video is kind of confusing. I have just read the original article and what he said is wrong, the body cell’s nucleus (in the video is called DNA, but DNA is located in the nucleus) couldn’t have fusion with another nucleus. That body cell’s nucleus was put in the cell in which was its nucleus removed so that dolly can exist. The explanation was ok, but the graphic description was not.

    The Invisible Crime “Illegal Microchip Implants and Their Use Against Humanity” Kindle Edition
    by Michael F. Bell (Author) Format: Kindle Edition
    A True Story
    An innocent man becomes the unwitting target of a secret criminal organization using high-tech weaponry, microchip implants, and mind control on its victims, leaving no evidence. The organization is covert, highly organized, well-funded, and uses the latest technology. This heinous, unconscionable crime has gone global—and rapidly has become a huge national problem.
    Author, Michael Fitzhugh Bell is drugged, abducted, raped, and surgically implanted with illegal microchip implants; all done without his knowledge or consent. Michael is tracked, stalked, and tortured, 24/7—and physically burned remotely with directed energy weapons which most people don’t even know exist. His every thought and feeling is being read in real-time by his perpetrators via GPS and current cellular satellite systems, making him, quite literally, a human piñata. Michael must prove his crime to the police and a judge before his attackers erase his memories and murder him.
    This story goes one step beyond Dr. John Hall’s own chilling tale of organized stalking by proxy. It is the author’s personal account of being electronically stalked and surgically implanted with micro-electronic transmission devices. It is the story of Michael’s uphill battle with doctors, lawyers, police, F.B.I., C.I.A., and a secret, global criminal union operating above the law. Beginning in Hollywood, California, Michael’s journey towards resolution will take him around the world—Madrid, Spain; London, England; Patagonia, Argentina; North and South Carolina, San Antonio, Texas; and back to southern California.
    This book contains medical evidence, M.R.I. and ultrasound images, all clearly showing non-therapeutic /tracking torture devices. Surprisingly, these devices are legal and are available for purchase by anyone on the Internet. They are known as psychotronic weaponry; combing the words psychological and electronic.
    Despite the most determined efforts to destroy him, Michael remains optimistic and focused, relentless in his pursuit to find his way out this never-ending terror and nightmare of a labyrinth that has become his life.
