Palantirkwa hili acha nikae na mchina mie🙂.
Reproductive cloning bado inawatia wanasayansi ukichaa kwa kushindwa kufanikiwa kabisa
Na ukisoma hapa chini vyema utagundua kwanini inashindwa kufanikiwa
When a human is conceived, a half of genetic material comes from mother (in the egg) and the other half from the father (in the sperm). With clones, whole genetic material comes from the donor. First. we need to remove maternal genetic material from the egg and then add the DNA of the subject we want to clone. Usually a light electric shock that starts cell division is needed.
Next, the early-stage embryo needs to be implanted in a surrogate mother. And in essence, that is how the clone is born. Of course, this is a complicated and difficult process, and many attempts are needed for it to succeed.
The first successfully cloned animal was sheep, Dolly, in 1996. Since then, science has made lots of different clones, but most of these ended tragically and died soon. The problem may be with cloning and that mutations that occur during that process, or it might be with the animal that was cloned. When the donors DNA samples are taken, the donor has already lived up to certain age. As a result, the DNA is aged and doesn’t function perfectly.
