篇1:有關克隆英語作文
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可靠地重現動物特殊的素質的有效途徑。例如,藥品生產的動物或動物已經轉基因作為研究人類疾病模型可以大量生產。
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。年輕的野牛死後出生48小時感染。2001,義大利的科學家們報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。克隆滅絕的動物提供了一個更大的挑戰,科學家因為雞蛋需要創造克隆胚胎將一種不同的代理從克隆的租金。
治療性克隆技術可能有一天被用於人類從單細胞或產生健康的細胞,可以替代退行性疾病如阿爾茨海默氏症或帕金森的多數作品受損細胞之前仍然需要治療性克隆可以成為治療病症的一種現實選擇產生整個器官。
篇2:有關克隆英語作文
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.
隨著我國科學技術的發展,克隆技術越來越接近我們的生活。看著另一個你可能會是一個有趣的,但是,一些人認為,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用在醫療使用。因此,我認為我們應該使用克隆,以使我們的生活變得更好。
篇3:有關克隆英語作文
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.
今天的技術發展得如此之快,以至於許多不可能的事情都變成了事實,克隆技術就是這樣的例子。什麼是克隆?克隆是一個通過使用正常的身體細胞的完整的遺傳物質來創造哺乳動物的精確副本的一個過程。不同於普通的繁殖,克隆只需要一個細胞,而不需要性。1997、好訊息震驚,英國科學家發明了一種燈從一個單細胞,命名為新子世界奇蹟;細胞已經被成年羊的乳腺,這表明第一個克隆實驗成功了。
當克隆技術提高得如此之快,許多科學家和醫生有不同的意見,有人認為這是好的,但有人認為這是壞的。克隆可以給人類帶來許多好處,如恢復,有助於有缺陷的基因,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癒,如果我們使用克隆技術,我們可以改變基因的DNA順序,所以我們可以節省很多人。
但克隆仍然存在一些問題。科學家們發現,克隆動物的基因與原來的動物有一點不同。這樣的生活會比現實生活短。事實證明,克隆羊新子已經死了。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。因為我認為克隆技術應該受到尊重。它確實可以給我們帶來許多好處,它可以進一步發展人類的科學。如果克隆人,會有很多問題,人口是最大的問題。可能有些人會用克隆人發動戰爭。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。***因為在美國,人權高於一切***
最後,我認為克隆是新技術,它應該被接受,如何看待這個技術,首先我們應該知道的優點和缺點,那麼我們應該知道人類和動物克隆的影響,第三我們將採取行動:倡導動物克隆但是反對與人類克隆
