Cloning
Today’s technology develops so quickly that many impossible things become true; the cloning technology is the example. What is cloning? Cloning is a process used to create an exact copy of a mammal by using the complete genetic material of a regular body cell. Different from the common propagate, cloning need only one cell and without sex. In 1997, the great news shocked the whole world that the British scientists created a lamp named Dolly from a single cell, miraculously; the cell had been taken from the udder of adult sheep, which show the first cloning experiment was successful.
When the cloning technology improves so quickly, many scientists and doctors have different opinions, someone think it is good but someone think it is bad. Cloning can bring many benefits to the human, such as rejuvenation, helpful for Defective genes, Liver failure, Kidney failure and Leukemia. These disease are very different to cure, if we use the cloning technology we can change the Gene’s DNA order, so we can save lots of people.

If Gray's first human anatomy solved the mystery of human structure, laid the foundation of modern medicine, but also to human beings a great deal of confusion. Nu Wa made man, the God will give to our eyes. There One day people use it for the first time in the water pleasantly surprised to see his own reflection, then people see themselves through the mirror, until now, people passed the gene of this particular mirror, to form a new look at ourselves, this look at the world . We are pleased to see that the use of broad prospects for genetic research. With the use of transgenic technology, daffodils rice genes have been implanted so that the iron content increased significantly; as people's understanding of gene cloning technology should be shipped born; first cloned sheep Dolly living people standing before; With the development of cloning technology, human organs can be cloned, is expected to take over with a new organ has been so old and damaged organs ....... all human beings seem to be as a second God, or Goddess of the second. Some say that God always answers in one hand, one hand and a question mark. Cloning is the English transliteration of the word clone, clone derived from the Greek klon The intention is that small seedlings or shoots to asexual reproduction or vegetative propagation means cultivating plants, over time, cloning has expanded the content, as long as the cells obtained from a more than 2 cells, cell populations or organisms by a pro-sequence generated by the sequence of DNA that is cloned. Clone as a double-edged sword. When the spring time, like to get people who will do grass cutting plant; a look like apples and pears taste like fruit - pear, is the use of fruit grafting culture from cuttings and grafting are essentially clones. is also a benefit to humanity. Cloning of human organs for medical development to a large extent, but is suffering from cancer or disability a gospel people. Cloning and generational relations between parents, as fathers of the human cloning, sub-generation, or the same seniority in the family or other, which we usually followed by old and young took part in starting the conflict, will be confusion all social relationships. human cloning is no kind of disrespect for human performance. human cloning, not just pieces of copy. If people are free to clone, that is, each person has countless lives. then revisit the value of life has no meaning. Does this also mean that life can be arbitrarily trampled on, and personality to any damage which in turn are usually emphasized in our respect for human life. life once they begin to talk about a person, if even on their own life autonomy are not, then what is the meaning of his survival of human cloning will benefit a mere careerist and lawless elements. We can not take into account the possibility of human cloning will lead soon as the war. careerist use human cloning to conquer the world, it seems science fiction can be seen. but in real life is not altogether unlikely. take advantage of human cloning committed crimes, crimes against personal safety even imagine. We should rationally look at cloning, it becomes beneficial to science and technology on human rather than the demise of human arms.如果說格雷的第一張人體解剖圖解開了人體結(jié)構(gòu)之迷,奠定了近代醫(yī)學(xué)的基礎(chǔ),但同時(shí)也給人類帶來很大的困惑.
女媧造人時(shí),上天便賜于我們眼睛.有一天人們用它第一次在水中驚喜地看見了自己的倒影,而后人們通過鏡子看自己,直到現(xiàn)在,人們又通過基因這一特殊的鏡子,以一種全新的形式審視自己,由此審視世界.
我們欣喜地看到了基因研究利用的廣闊前景.隨著轉(zhuǎn)基技術(shù)的運(yùn)用,水仙的基因已被植入水稻,使之含鐵量明顯的增高;隨著人們對(duì)基因的了解,克隆技術(shù)應(yīng)運(yùn)而生;第一只克隆羊多利活生生地站在了人們面前;隨著克隆技術(shù)的發(fā)展,人類的器官可以被克隆,有望用新器官接替我們已老損的器官.......如此種種讓人類似乎已可充當(dāng)?shù)诙€(gè)上帝,或者說第二個(gè)女媧了.有人說上帝總是一手拿著答案,一手拿著問號(hào).
克隆是英語(yǔ)單詞clone的音譯,clone源于希臘文klon,原意是細(xì)苗或嫩枝以無(wú)性繁殖或者營(yíng)養(yǎng)繁殖的方式培育植物,隨著時(shí)間的推移,克隆的內(nèi)涵已經(jīng)擴(kuò)大了,只要是由1個(gè)細(xì)胞獲得2個(gè)以上的細(xì)胞,細(xì)胞群或生物體,由一個(gè)親本序列產(chǎn)生的DNA的序列,就是克隆.
克隆就如一把雙刃劍.
每當(dāng)春暖花開的時(shí)候,喜歡弄草的人便會(huì)做植物扦插;一種外觀像蘋果而味道似梨的水果—蘋果梨,就是采用果樹嫁接法培養(yǎng)而成的,扦插和嫁接實(shí)質(zhì)上也是克隆.也是對(duì)人類的好處.克隆人體器官對(duì)醫(yī)學(xué)發(fā)展也有很大促進(jìn)作用,更是對(duì)身患癌癥或殘疾人的一個(gè)福音.
克隆人與親本間的輩分關(guān)系,克隆人該是作為父輩,子輩或同一輩分或者是其它,這與我們平常所遵循的長(zhǎng)幼有分起了矛盾,也會(huì)混亂各種社會(huì)人際關(guān)系.
克隆人是對(duì)人的不種不尊重表現(xiàn).克隆人,就不只是件復(fù)制品.倘若人可以隨意克隆,那就是就每個(gè)人都擁有無(wú)數(shù)次生命.此時(shí)再講生命的價(jià)值已毫無(wú)意義了.這是否也意味著生命可以任意踐踏,人格可以任意傷害 這又與我們平時(shí)所強(qiáng)調(diào)的尊重每個(gè)人的生命.生命只有一次又從何談起 一個(gè)人,如果連對(duì)自已生命的自主權(quán)都沒有,那他的生存意義何在
克隆人會(huì)給野心家和不法分子有利可乘.我們不能不考慮到有可能克隆人將引發(fā)一聲戰(zhàn)爭(zhēng).野心家利用克隆人征服全球,這似乎在科幻小說中才能見到.但現(xiàn)實(shí)生活中并不是完全不可能.而利用克隆人作案,危害人身安全更是可想而知.
我們應(yīng)該理智地看待克隆,將它變?yōu)閷?duì)人類有利的科學(xué)技術(shù)而非人類走向滅亡的武器.
While cloning provides many immediately obvious benefits,it also opens a Pandora box that will destroy social orders as we know it.Human society functions based on succession of generations and on each generation's DNA being different from the previous.With cloning,both of those will be changed forever.Cloning will allow those who can afford to produce fully transplantable organs to replace their aging organs and therefore possibly live to be hundreds of years old.Some may attempt to clone a complete copy of themselves and it means two generations will have exactly the same genetic composition.With line of generations blurred and unique genetic compositions across generations no longer a guarantee,human society as we know it will no longer be possible.And once this Pandora box is opened,it can never be closed again.
There are some rare endangered animal, country has the giant panda, dolphin and so on. Cloning technology can use them? The pair of pandas for cloning problems, has caused controversy among scientists concerned, then, cloning of endangered animal also exist what difficulty? These difficulties there may be overcome? The difficulty is in endangered species of wild animal animal compared to ordinary world, present a minimal amount of available for cloning experiments, individual is less. The baiji as an example, the remaining also foot 100, Wuhan dolphin hall wife raise " cake ", is available to scientists cloning experiments on a few individuals, but it is a male, even if successful cloning, finally the clone son may also be governed by it to do "" surrogate mother ". Dolly's birth process, scientists used a total of 3 " false mother ", use a total of 277 embryos will succeed in the end. The difficulties of two so far, there are many endangered wild animal growth process, living habits and to grasp. The class has been successfully cloned sheep, rabbits, pigs, monkeys and other animal, for they live well, cloning of these animal course than cloning of wild animal much easier, the success rate is much greater. Difficult three some endangered animal 's special living environment, caused scientists clone their process will encounter many thought. For example, because it is a streamlined life in the water, it lives in the land of Ganges RIver sheep, monkey, living environment is the same, so cloning experiments, the process, technical difficulty of operation will increase. Therefore, due to save these difficulties, in theory, although cloning endangered wild animal is feasible, but, depending on the cloning technology to save endangered animal the possibility is very small. However, with the cloning of progress and development, believe scientists will gradually overcome some difficulties, let the cloning of endangered wild animal ideal truly, make these precious animal classes become friends, let them long to become a part of the world.
以上就是克隆的英語(yǔ)作文的全部?jī)?nèi)容，about cloning, by no means should we give in to the unsolved problems.至于我，我認(rèn)為克隆對(duì)提高我們的生活質(zhì)量還是有很重要作用的。更不用說，克隆不僅可以幫助我們了解許多關(guān)于生物的未知問題，而且它還是一項(xiàng)很好的突破。盡管現(xiàn)在克隆上還有著許多難題，但是絕不意味著我們就要為這些難題而讓步。
