Magical cloning read cloning technology Read the answer

1. The article first uses the myth ** ("Journey to the West") to introduce the cloning phenomenon of cloning (magical) and then classifies and introduces the cloning phenomenon of (plants) bacteria and sheep, and finally tells us that cloning technology can (benefit mankind), and magical cloning (is showing its attractive prospects to mankind. ）

2. I want to clone (pandas), because (now pandas are rare animals and are about to become extinct, I hope that there will be more and more pandas, not extinction).

3. "Higher animals generally need to be combined by male and female germ cells in order to reproduce offspring. Can the dotted word (generally) be deleted from this sentence? Please tell us why.

A: No, you cannot. Because "general" means that not all higher animals need to combine male and female germ cells in order to reproduce, but most higher animals need to be combined by male and female germ cells in order to reproduce.

"Journey to the West") leads to the cloning (magical), then classifies and introduces the cloning phenomenon of (plants), lower organisms, and higher organisms), and finally tells us that cloning technology can (benefit mankind), and magical cloning (is showing mankind its attractive prospects).

1.enabling the efficient reproduction of high value-added livestock; saving rare and endangered animals; It is convenient for people to study cancer biology, immunology, and human lifespan.

2.It shows that cloning technology will bring great benefits to human beings, and the cloned organisms contain many beneficial substances with high added value.

3.It is said that cloning technology has advantages and disadvantages, and the advantage is that it can provide people with "accessories" for themselvesBut it can also cause chaos in society and provide opportunities for criminals to take advantage of.

4.It illustrates the benefits and effects of cloning technology for the benefit of mankind.

, (1) cloning.

Special dairy goat and dairy cows, serving human health; (2) cloning the mule, an animal with special heterosis to serve humans; (3) cloning pandas and saving rare animals; (4) Cloning animals is also conducive to the study of cancer biology, immunology, and human lifespan. (5) Clone human organs and provide "accessories" for human beings. 2.

Omitted 3For example, it is difficult to determine the identity of a clone, the role of the family is difficult to determine, whether the clone is a "human" or not, and so on.

Cloning technology will bring great benefits to humans, for example, the British company PPL has bred ewes with emphysema A-1 antitrypsin in goat's milk. The price of this goat's milk is $6,000 a liter. A ewe is like a pharmaceutical factory, what is the most effective and convenient way to expand the breeding of this sheep?

The best way to do this is to "clone". Similarly, how can these high value-added livestock be effectively bred by PHP in the Netherlands and LAS in Israel to produce serum albumin? The answer, of course, is "cloning".

Mare and male donkey can get a particularly strong "hybrid" advantage of the animal - mule, but mules cannot reproduce offspring, so how can a good mule expand breeding? The best way is also to "clone", China's giant panda is a national treasure, but the success rate of natural mating is low, so it is on the verge of extinction. How can this rare animal be saved?

"Cloning" provides a practical path for humanity.

In addition, animal cloning has a role that cannot be underestimated in the study of cancer biology, the study of immunology, and the study of human lifespan.

Admittedly, the advent of "cloned sheep" has also aroused the interest of many people in "cloning people", for example, some people are considering whether it is possible to clone their own cells into an embryo and freeze it before it takes shape. One day in the future, when one of its own organs fails, it can be taken out of the embryo for culture, and then replace its diseased organs, which is to use cloning to provide "accessories" for human beings.

The discussion of "human cloning" is a reminder that technological progress is a march of mixed joy and sorrow. The more technology develops and the more extensive and in-depth it penetrates into society, the more likely it is to give rise to many ethical, moral, and legal issues.
