Human reproductive cloning. How does cloning work?
What will actually happen if you clone yourself?
Cloning proves to be more difficult than finding an ancient mosquito in amber. Human cloning, in particular, is so difficult that this fantastic performance has not yet been achieved. In any case, nothing is known about such an event.
In part, cloning is a matter of technology. Humans are complex and sensitive beings, starting with our DNA. But, given that animal cloning has existed since the 1990s, more importantly, human cloning is a hot political issue and one that does not cause much controversy among citizens. Moreover, the number of opponents of cloning has only increased over the years. Few questions have this level of consensus – and scientists largely agree. In 2003, 60 different scientific academies around the world called on the United Nations to completely ban any attempt at human cloning.
But today, laws against human cloning are quite limited, and there are more and more rumors that such technology is almost available every year. So you can forget old statements like “two identical objects cannot occupy the same space. You will certainly not destroy the universe by embracing your clone.
Human cloning is just a complex engineering task, so despite public opinion, it is likely to be inevitable in the very near future.
But it is important to remember that unlike Blade Runner’s full-fledged “replicants” and similar blockbusters, a human clone will almost certainly grow from an embryo.
Let’s see what happens if you can clone yourself.
Cloning a human being is not only difficult, it is extremely difficult. Until now, this has not been possible, mainly because of the unique structure of our germ cells. There is an inexplicable and strange difference in the degree of difficulty in cloning seemingly similar animals.
I don’t think anyone realized how difficult it would be to clone some species, but relatively easy for others, said Hank Greeley, a Stanford bioethicist. Cats: easy; dogs: difficult; mice: easy; rats: difficult; humans and other primates: very difficult.
Since the late 1990s, several scientists have claimed to have broken the code for human cloning, however, according to the National Human Genome Research Institute, the facts do not support these claims.
Cloning oneself or other genetically related primates most likely involves removing the nucleus from a donor egg to replace it with an adult cell nucleus. But in primate eggs (and humans are primates), a pair of proteins needed for cell division, called fused proteins – kinetochores, are so close to each other that handling this sensitive cell removes all the important components for growth. And that’s the real problem.
