What happened to the clone Dolly ? What are the disadvantages of cloning technology?

Dolly grew up suffering from illness and died of geriatric disease at a young age. Disadvantages: 1. There are many theories about Dolly's death, one is that clonal life itself has premature aging, so their lifespan is shorter than that of normal life.

2. From Dolly's point of view, it is only about half of the normal lifespan Another theory is that Dolly's nucleus is taken from a sheep that is already 6 years old, so when it is born, it is actually equivalent to the 6 years old of a normal goat, and it only has the second half of its life to live. 3. Some people think that Dolly's living environment in captivity will itself increase the possibility of getting sick.

Dolly the cloned sheep ended up living a short lifespan, and there were many diseases in the late stage, which was eventually preserved as a specimen.

Disadvantages of cloning sheep:1Ethical issues arise.

2.Cloning technology is immature and can lead to many diseases. 3.

It can be used by criminals. 4.will change the diversity of society.

5.It will undermine the ethics and morals of mankind.

The cloned sheep suddenly had a serious progressive lung disease, and the condition was menacing, and it was difficult for everyone to treat it, so it could only be euthanized. The cloned sheep suffered from severe joint disease before they died, and this change is only seen in old age. Should clones have the same rights and obligations as normal people, what should they do if the clones fail, and what should they do if they are scheduled to do bad things?

These are all things that cannot be solved by current science and technology.

It's not very good, because during this period of life, the body is not very healthy, the resistance is very weak, the genetics of this technique will be disordered, and the body's own resistance will be weakened.

Dolly the sheep is cloned by the scientific method of egg cell replication, but this method can also be flawed, such as the phenomenon of premature aging. Dolly the sheep died because of premature aging.

Produced by somatic cell nuclear transfer technology, the approximate steps are: implanting the mammary nucleus of a female sheep into an unfertilized egg with the nucleus removed from another female sheep to form a blastocyst; It is then transplanted into the womb of the third ewe, which is pregnant and gives birth to a young sheep that is genetically identical to that of the donor ewe. The genetic traits of the resulting sheep are almost identical to those of the donor sheep, which can be said to be a replica of the asexual reproduction of the donor sheep, that is, the "cloned sheep".

This is because this cloning technology has many drawbacks, there are certain limitations, and the final experimental results are unsatisfactory, and there is no way to apply it to people, so it is not advocated now.

This is because there are many drawbacks in cloning technology, although the cloning of Dolly sheep has been successful, but the cloning of Dolly sheep carries a lot of diseases after birth, so it is not advocated now.

Because man is a unique animal, and it is also unique, no one can copy it, which will cause some drawbacks.

It's not that cloning technology has failed, it's that cloning technology is immature.

In elementary school textbooks, it appears that the British once cloned a lamb and named it Dolly. These represent the continuous progress of science and technology, but it is worth noting that Dolly only lived 6 and a half years before dying, why did she live half as long as other sheep? <>

It can be said to be the first animal in human history to be "copied and pasted" through cloning technology, which caused a lot of sensation in the world at that time, and it was also written into textbooks, and I believe that many people still remember what it looked like. At that time, the cloning technology was not fully mature, and after three years, the disadvantages of this technology were also reflected in Dolly, which began to show obvious aging, and the rate of aging was much faster than that of ordinary sheep. <>

At the same time, other lambs bred by mothers and wombs are very physically strong, while little Dolly is gradually losing immunity and often getting sick, which has attracted the attention of scientists. Moreover, since Dolly was born, there have also been cloned monkeys, cloned pigs and other animals, but these animals have also been constantly sick and even died early. So the scientists studied Dolly again, and later it seemed that they had figured out the truth of the matter.

Everyone knows that Dolly is an animal that "assists and pastes", but in the process of pasting, the DNA cannot be completely pasted, so in Dolly's body, its DNA telomeres are short, and telomeres are related to the degree of aging, so with the growth of time, its telomeres will gradually decrease, and its aging speed will become faster and faster. <>

Normal sheep die at about 12 years old, but due to the peculiarity of Dolly's DNA telomeres, it died at the age of 6, but its carcass has been made into a specimen and stored in the National Museum of Scotland, after all, its appearance represents the technological progress of mankind and also exposes the unreliability of cloning technology.

It cannot be said that the cloning technology is a failure, but that the cloning technology is not mature enough, so it will lead to the life span of sheep being shortened so much, which is against the laws of nature.

It can't be said to be a failure, cloning refers to asexual reproduction, Dolly's birth actually means success, Dolly, who only lived for more than 6 years, died of progressive lung disease, this disease is a common disease in Mianyang, especially indoor breeding, and Dolly itself is extremely special, this disease happens to be an incurable disease, Dolly can not ** and die, and Dolly's birth involves a lot of experiments, and the damage of these experiments to it should not be underestimated.

That's because China now doesn't allow the casual use of cloning technology, so people don't pay attention to this aspect anymore, and the later cloned sheep also lived and died not long after.

This is because it will cause a lot of damage to the sheep, so no one says that the sheep are cloned, relatively speaking, the sheep may have died, or they may have been killed.

This is because there has not been much development in cloning technology over the years, and the life span of cloned organisms is very short, so cloned sheep later die.

Because the first cloned sheep, Dolly, is dead. The lifespan of cloned sheep Dolly is still reduced by cloning, and cloning technology needs to be used more carefully.

Because cloning technology is a failure. Dolly is now dead. Cloning technology is dangerous.
