Cloning is the hope of human organ transplants
If the cloned embryo to adult culture, to obtain from him some "spare parts" - organs as transplants, but we how can a person (because human cloning are people too!) Any who made his organs? The cloning of human organs is a feasible way to resolve the scientists bred a headless human cloning for organ transplant, so that the supply of human organs factory, in order to solve the shortage of organs for transplant. However, this approach is in the end the feasibility acceptable basic principles of the international community need to match.
The generalized clone refers to every from an ancestor, passes through vegetative reproduction crowd of individuals.
But if its application in human
Conclusion:
In my opinion cloning have advantage and disadvantage,so we can’t only on the upside or on the down-side ,the key is to look at human beings how to use it.We should be good to the use of cloning technology to do more useful things for mankind.
Will the Cloned Einstein to understand the "theory of relativity" ??
clone is good or not??
Research advances over the past decade have told us that, with a little work, we humans can clone just about anything we want, from frogs to monkeys and probably even ourselves! So, we can clone things, but why would we want to? Let's look at some of the reasons people give to justify cloning.
5、From the biodiversity, the massive gene structure identical clone, possibly induces the new disease's widespread dissemination, is disadvantageous to humanity's survival. 6、 The clone counteracts in the human dignity, will cause to create one new slavery the condition. 7、The clone will give humanity's ethics system to bring “the sentimental black hole”, henceforth has cancelled the life sacred feeling, between people's sentiment greatly will possibly sell at a discount

There are people who are on the up-side of cloning
Humanity is plagued with many moral issues each day. With recent announcement that a research facility in England had successfully cloned a sheep, many more questions arose. The overall question is , "To clone or not to clone?" Many groups worldwide, doctors, politicians, religious people, have been battling with this question. Many doctors believe cloning is an advancement to help save more people's lives. Although specific organs or rare blood types have yet to be cloned and actually made available to the general medical community. Think about it: if someone desperately needed a liver transplant because they drank too much alcohol, with the aid of cloning technology, doctors would be able to clone that person's liver cells and produce a healthy, genetically matched liver, thus saving that patient's life. Cloning could revolutionize the medical industry! While many doctors are on the up-side of cloning, many politicians are on middle ground. Many see the medical need, but are reluctant. Most politicians want something for themselves for their endorsement either way on an important issue. Since cloning is not yet ready to be made accessible, by any means, to the general public, it is not yet a major issue to politicians. Since politicians make the laws worldwide, we will have to wait and see whether cloning is legal all out, only parts and specific uses legal, or all illegal.

1. What was the first cloned mammal? What happened to her?
It was a sheep named Dolly in 1996.
At first, Dolly grew normally. But later she developed an illness that is more normally found in much older animals. She lived for six and a half years, only half the life of the sheep from which she was cloned.
Summary
Complete the summary using the information in the article.
Natural cloning has taken place for generations. An example of this is identical 1 __tw__in_s___. A sheep called Dolly was the first mammal to be cloned 2 _a_r_t_if_i_c_ia_l_ly_. Since Dolly, more than 20 mammal 3 __sp_e_c_i_e_s___ have been cloned including camels and goats. In 2018, China announced that two monkeys had been cloned.

What is cloning ?
• Cloning is the creation of cells
or whole animals using DNA from a single "parent", by passing the normal reproductive process. The clone has the same DNA to the parent.
Simplified Man's paternity Disrupted generational relation Individuals become isolated individuals Social network will become more complicated All of these will strongly threaten the traditional natural ethical relations、moral rules and political system.
Should Humans be cloned?
• Although the possibility of cloning humans has been the subject of speculation for much of the twentieth century, scientists and policy makers began to take the prospect seriously in the 1960s. • When asked whether scientists should be able to clone human, 85% said no, 11% said yes.

• 体细胞杂种通常由人和鼠的体细胞融合而成。这些 融合细胞在最初几代培养过程中具有选择性丢失人 类染色体趋势，而保留所有的鼠染色体。
• 保留在融合细胞中的染色体可以是多条，也可能只 有一条甚至某条染色体的一部分。
• 根据研究的需要可将含有不同人类染色体的人鼠杂 种细胞组合成人鼠杂种细胞板(hybrid panel)，结 合杂种细胞板和PCR的方法或基因剂量分析，或蛋 白质表达分析，可将相应的基因定位到特定的染色 体或染色体片段上，该杂种细胞板在人类基因定位 以及人类基因组计划中发挥过重要的作用。

连锁分析原理
生殖细胞在减数分裂时发生交换，一对同源染色体 上存在着两两相邻的基因座位，若两者之间距离较 远，发生交换的机会较多，则出现重组次数就多； 若两者之间距离较近，则重组机会较少。
克隆英语介绍演讲稿
克隆英语介绍演讲稿English: Cloning is the process of creating a genetically identical copy of an organism through asexual reproduction. This can be done using various techniques, such as embryo splitting, nuclear transfer, or artificial cloning. Cloning has been a subject of controversy and debate, especially in the context of cloning humans. However, cloning has also shown potential in various fields, such as medicine, agriculture, and conservation. In medicine, cloning has the potential to produce organs and tissues for transplantation, while in agriculture, it can be used to create genetically superior livestock and crops. Cloning also holds promise for the conservation of endangered species by creating genetic copies of individuals.中文翻译: 克隆是通过无性繁殖创造一个基因上与原生物相同的复制体的过程。
这可以通过各种技术来实现，比如胚胎分裂、核转移或人工克隆等。
克隆一直是一个备受争议和辩论的话题，特别是在克隆人类的情境下。
