篇1：有關(guān)克隆英語作文
Increased food security for growing populations
If the low success rates can be improved (Dolly was only one success out of 276 tries)reproductive cloning can be used to develop efficient ways to reliably reproduce animals with special qualities.For exampledrug-producing animals or animals that have been genetically altered to serve as models for studying human disease could be mass-produced.
Reproductive cloning also could be used to repopulate endangered animals or animals that are difficult to breed.In 2001the first clone of an endangered wild animal was borna wild ox called a gaur.The young gaur died from an infection about 48 hours after its birth.In 2001scientists in Italy reported the successful cloning of a healthy baby mouflonan endangered wild sheep.The cloned mouflon is living at a wildlife center in Sardinia.Other endangered species that are potential candidates for cloning include the African bongo antelopethe Sumatran tigerand the giant panda.Cloning extinct animals presents a much greater challenge to scientists because the egg and the surrogate needed to create the cloned embryo would be of a species different from the clone.
Therapeutic cloning technology may some day be used in humans to produce whole organs from single cells or to produce healthy cells that can replace damaged cells in degenerative diseases such as Alzheimer's or Parkinson's.Much work still needs to be done before therapeutic cloning can become a realistic option for the treatment of disorders.
增加糧食安全的人口增長
如果低成功率可以提高(新子只有一個成功了276次)，生殖性克隆可以用來開發(fā)可靠地重現(xiàn)動物特殊的素質(zhì)的有效途徑。例如，藥品生產(chǎn)的動物或動物已經(jīng)轉(zhuǎn)基因作為研究人類疾病模型可以大量生產(chǎn)。
生殖性克隆也可以用來填充瀕危動物或動物是很難繁殖。2001、瀕危野生動物的第一個克隆人的誕生，野牛稱為野牛。年輕的野牛死后出生48小時感染。2001，意大利的科學(xué)家們報(bào)道了一個健康的寶寶摩弗倫羊的克隆成功，瀕臨滅絕的野羊，克隆摩弗倫羊是生活在撒丁島的一個野生動物中心。其他瀕危物種，克隆的潛在候選人包括非洲邦戈羚羊，蘇門答臘虎，和大熊貓?？寺缃^的動物提供了一個更大的挑戰(zhàn)，科學(xué)家因?yàn)殡u蛋需要創(chuàng)造克隆胚胎將一種不同的代理從克隆的租金。
治療性克隆技術(shù)可能有一天被用于人類從單細(xì)胞或產(chǎn)生健康的細(xì)胞，可以替代退行性疾病如阿爾茨海默氏癥或帕金森的多數(shù)作品受損細(xì)胞之前仍然需要治療性克隆可以成為治療病癥的一種現(xiàn)實(shí)選擇產(chǎn)生整個器官。
篇2：有關(guān)克隆英語作文
With the development of our science and technology cloning becomes more and more close to our lives. Looking at another you probably could be a fun however some people think that it will bring a lot of trouble such as how to identity which one is real. In my opinion we do not need to clone a whole body of you. For example when you lose one of your fingers they can just clone a new finger for you. And that would a very good application in medical use. Thus I think that we should use the clone to make our life better off.
隨著我國科學(xué)技術(shù)的發(fā)展，克隆技術(shù)越來越接近我們的生活?？粗硪粋€你可能會是一個有趣的，但是，一些人認(rèn)為，它會帶來很多麻煩，如如何身份，這是一個真正的。在我看來，我們不需要克隆你的整個身體。例如，當(dāng)你失去了你的一個手指，他們可以為你克隆一個新的手指。這將是一個很好的應(yīng)用在醫(yī)療使用。因此，我認(rèn)為我們應(yīng)該使用克隆，以使我們的生活變得更好。
篇3：有關(guān)克隆英語作文
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.
But cloning still has some problems. The scientists found that the cloning animal’s Gene has a little different from the original animal. So the life will shorter than the real life. The fact proved that the cloning sheep Dolly has died. It only has the half life of the common sheep.
In my own opinion I agree to clone the endangered animal and disagree with cloning human. Because I think the cloning technology should be respected. It really can bring us many benefits; further more it can develop the science of human. If clone the human there will however be many problems the population is the biggest problem. May be some people will use the cloning people to start the war. So I am against cloning human.
Also many countries disagree to clone people. The government makes the laws about cloning. There are laws against human cloning in Canada Denmark England Norway Spain and the UK. Even in the USA the government doesn’t allow to clone human. (Because in USA the human right is higher than everything)
In the end I think cloning is new technology it should be accepted how to look upon this technique first we should know the advantages and disadvantages then we should know the effect of cloning for human and the animal third we will take the action: To advocate the animal cloning but be against with the human cloning.
今天的技術(shù)發(fā)展得如此之快，以至于許多不可能的事情都變成了事實(shí)，克隆技術(shù)就是這樣的例子。什么是克隆?克隆是一個通過使用正常的身體細(xì)胞的完整的遺傳物質(zhì)來創(chuàng)造哺乳動物的精確副本的一個過程。不同于普通的繁殖，克隆只需要一個細(xì)胞，而不需要性。1997、好消息震驚，英國科學(xué)家發(fā)明了一種燈從一個單細(xì)胞，命名為新子世界奇跡;細(xì)胞已經(jīng)被成年羊的乳腺，這表明第一個克隆實(shí)驗(yàn)成功了。
當(dāng)克隆技術(shù)提高得如此之快，許多科學(xué)家和醫(yī)生有不同的意見，有人認(rèn)為這是好的，但有人認(rèn)為這是壞的?？寺】梢越o人類帶來許多好處，如恢復(fù)，有助于有缺陷的基因，肝功能衰竭，腎功能衰竭和白血病。這些疾病是非常不同的治愈，如果我們使用克隆技術(shù)，我們可以改變基因的DNA順序，所以我們可以節(jié)省很多人。
但克隆仍然存在一些問題。科學(xué)家們發(fā)現(xiàn)，克隆動物的基因與原來的動物有一點(diǎn)不同。這樣的生活會比現(xiàn)實(shí)生活短。事實(shí)證明，克隆羊新子已經(jīng)死了。它只有普通綿羊的半衰期。
在我看來，我同意克隆瀕危動物，不同意克隆人類。因?yàn)槲艺J(rèn)為克隆技術(shù)應(yīng)該受到尊重。它確實(shí)可以給我們帶來許多好處，它可以進(jìn)一步發(fā)展人類的科學(xué)。如果克隆人，會有很多問題，人口是最大的問題?？赡苡行┤藭每寺∪税l(fā)動戰(zhàn)爭。所以我反對克隆人類。
也有許多國家不同意克隆人。政府制定有關(guān)克隆的法律。在加拿大、丹麥、英國、挪威、西班牙和英國都有針對克隆人的法律。即使在美國，政府也不允許克隆人類。(因?yàn)樵诿绹藱?quán)高于一切)
最后，我認(rèn)為克隆是新技術(shù)，它應(yīng)該被接受，如何看待這個技術(shù)，首先我們應(yīng)該知道的優(yōu)點(diǎn)和缺點(diǎn)，那么我們應(yīng)該知道人類和動物克隆的影響，第三我們將采取行動：倡導(dǎo)動物克隆但是反對與人類克隆
