克隆的议论稿

克隆的议论稿

我们所说的生物技术的利和弊主要指的是克隆,其利和弊是利:1) 克隆技术可解除那些不能成为母亲的女性的痛苦。

2) 克隆实验的实施促进了遗传学的发展,为“制造”能移植于人体的动物器官开辟了前景。

3) 克隆技术也可用于检测胎儿的遗传缺陷。

将受精卵克隆用于检测各种遗传疾病,克隆的胚胎与子宫中发育的胎儿遗传特征完全相同。

4) 克隆技术可用于治疗神经系统的损伤。

成年人的神经组织没有再生能力,但干细胞可以修复神经系统损伤。

5) 在体外受精手术中,医生常常需要将多个受精卵植入子宫,以从中筛选一个进入妊娠阶段。

但许多女性只能提供一个卵子用于受精。

通过克隆可以很好地解决这一问题。

这个卵细胞可以克隆成为多个用于受精,从而大大提高妊娠成功率。

弊:1) 克隆将减少遗传变异,通过克隆产生的个体具有同样的遗传基因,同样的疾病敏感性,一种疾病就可以毁灭整个由克隆产生的群体。

可以设想,如果一个国家的牛群都是同一个克隆产物,一种并不严重的病毒就可能毁灭全国的畜牧业。

2) 克隆技术的使用将使人们倾向于大量繁殖现有种群中最有利用价值的个体,而不是按自然规律促进整个种群的优胜劣汰。

从这个意义上说,克隆技术干扰了自然进化过程.3) 克隆技术是一种昂贵的技术,需要大量的金钱和生物专业人士的参与,失败率非常高。

多莉就是277次实验唯一的成果。

虽然现在发展出了更先进的技术,成功率也只能达到2-3%。

4) 转基因动物提高了疾病传染的风险。

例如,如果一头生产药物牛奶的牛感染了病毒,这种病毒就可能通过牛奶感染病人5) 克隆技术应用于人体将导致对后代遗传性状的人工控制。

克隆技术引起争论的核心就是能否允许对发育初期的人类胚胎进行遗传操作。

这是很多伦理学家所不能接受的。

6) 克隆技术也可用来创造“超人”,或拥有健壮的体格却智力低下的人。

而且,如果克隆技术能够在人类中有效运用,男性也就失去了遗传上的意义。

7) 克隆技术对家庭关系带来的影响也将是巨大的。

一个由父亲的DNA克隆生成的孩子可以看作父亲的双胞胎兄弟,只不过延迟了几十年出生而已。

Humancloning克隆对人类有好处正方演讲稿

Humancloning克隆对人类有好处正方演讲稿

Human Cloning benefitsAt first ,I should declare one thing-we do not admit every types of cloning,only the ones when is necessary and safety.I would like to cut straight to the themeThe human cloning situations which are considered most frequently has three categories:1.Parents who want to clone a child,either to provide transplants for a dying child or to replace that child directly.2.Adults who want to clone themselves in order to prolong theirs lifespan by transporting one’s consciousness from one body to another .3.Mad scientists who would like to clone famous people,or notorious bad guys, whatever ,clone human beings in quantities,which may cause an unordered social state.The three topics are what I am going to talk about.In the first case, we should reach to an agreement.before anything-that there are no parents who want to clone their children deadly, are not definitely cool-headed and serious.I means.all the parents who agree to clone their children are ready.They can take the responsibilities,of course.If they want to clone a baby to replace thedying one,it’s OK.They will look after him just like a nurtural newborn one,which looks very similar to his dead brother,or her dead sister.There have no questions. And in the other hand, clone a baby, who can provide transplants for the one who is dying now,in some peoples’mind,seems like caring nothing about the human rights of the babies.But is it unusual?There are thousands of women who accept an induced abortion surgery everyday in this world.What they had done are to ignore the fact that so many women are both damaging their health and just leave the babies’rights off the door, and arrest the parents who just want see their children growing up. They are killing the possibilities for parents to regain their sweet homes. They care the minority, not the majority. How clever they are!And then, the second case, frankly speaking,was totally fiction. It is said that we got no evidence which can prove that consciousness can transport between different bodies. But with the use of transplants from a cloned human,the original human could truly prolong his life in that way.But in our opinion,that actions are not included in the proper using of cloning. We do not accept every types of cloning, like what I said just now-we are in favor of two types of cloning only-The cloning for heart broken parents and for medical use when essential.Transplants for a health man will never be accepted.And the last one,which we think,lack the basic knowledge about cloning. First, the cloning technology is difficult, very difficult to reach a certain number, even if thereare so few clones will come into the world, may not be the threat to human survival. Secondly, the acceptance of things that people have a process, the human moral concepts can be changed, and now can not accept what the future may not be acceptable.the development of technology has its own internal rules, the cell technology is unstoppable. Even if people disagree on the cloning of people do not say categorically do not need to engage in human society, human cloning.Human cloning research will address some theoretical issues in developmental biology provide an opportunity, but also may provide useful technique to humans. Do not always think about the ethics of human cloning, legal and moral, which easily tied the hands of scientists and creativity.If fully coordinate the scientific and social values, individual values and group values, temporary and long-term value of the relationship between the value, to help improve the quality of human survival and sustainable development criteria, as our values, cloning technology itself will be in play and social development in the future of its great potential. As long as it is conducive to improving the quality of human survival and sustainable development of cloning technology as a standard of value, can make them better for the cloning of human and social services.。

Cloning technology has emerged as one of the most contentious topics in contemporary science. While it holds promises for medical advancements and genetic research, it also raises profound ethical, moral, and societal concerns. In this essay, we will delve into the intricacies ofcloning technology, exploring its potential benefits and ethical dilemmas.Firstly, it is imperative to understand the scientific basis of cloning. Cloning involves the creation of genetically identical copies of organisms, cells, or DNA fragments. There are several methods of cloning, including somatic cell nuclear transfer (SCNT), where the nucleus ofa somatic cell is transferred into an egg cell whosenucleus has been removed, and reproductive cloning, which aims to create a new individual organism.One of the most significant potential benefits of cloning technology lies in its applications in medicine. Cloning can be instrumental in producing genetically identical animals for biomedical research, allowing scientists to study diseases and develop new treatments. Moreover, therapeutic cloning holds promise for generating tissues and organs for transplantation, thereby addressing the shortage of donor organs and reducing the risk of organ rejection.However, the ethical implications of cloning cannot be overlooked. One of the primary concerns is the moral status of cloned organisms. Critics argue that cloning undermines the uniqueness and dignity of individual beings, raising questions about identity and autonomy. Moreover, there are fears of exploitation and commodification of cloned organisms, particularly in commercial contexts.Another ethical dilemma associated with cloning is the potential for misuse and abuse. Cloning technology could be misappropriated for purposes such as reproductive cloning of humans, which raises profound ethical, social, and legalconcerns. The prospect of cloning humans raises questions about individuality, family dynamics, and the sanctity of life.Furthermore, cloning technology poses significant challenges to societal norms and values. It blurs the boundaries between natural and artificial, challenging traditional notions of reproduction and parenthood. The prospect of designer babies, where genetic traits can be manipulated and selected, raises concerns about eugenics and social inequality.In addition to ethical concerns, there are practical limitations and risks associated with cloning technology. Cloned organisms often suffer from health issues and abnormalities, leading to high rates of morbidity and mortality. Moreover, the process of cloning is technically challenging and inefficient, with a low success rate and high cost.In conclusion, cloning technology represents a double-edged sword, with the potential for significant benefitsand profound ethical dilemmas. While it holds promises for medical advancements and genetic research, it also raises fundamental questions about identity, autonomy, and the sanctity of life. As we navigate the complexities of cloning technology, it is essential to approach it with caution, ensuring that ethical considerations and societal values guide its responsible development and application.。

克隆技术这篇作文

克隆技术这篇作文

克隆技术这篇作文在如今这个科技飞速发展的时代,各种新奇的技术层出不穷,其中就有让人惊叹不已的克隆技术。

说起克隆技术,我就想起了之前的一次特别经历。

那时候,我去参加了一个科技展览,展览上展示了各种各样的前沿科技成果,而其中最让我驻足停留、反复琢磨的,就是关于克隆技术的展示区域。

那个展示区域布置得十分精心,有巨大的屏幕播放着关于克隆技术的介绍视频,还有详细的图文展板,旁边甚至摆放着一些克隆实验的模型和样本。

我好奇地凑上前去,眼睛紧盯着那些展示品,仿佛要把每一个细节都看穿。

展板上的图片清晰地展示了克隆的过程。

从一个小小的细胞开始,经过一系列复杂而精细的操作,竟然能够复制出一个与原个体基因完全相同的新生命。

这让我感到既神奇又有些不可思议。

我想象着,如果能够随心所欲地克隆出任何东西,那这个世界会变成什么样呢?正当我陷入沉思时,旁边的一个工作人员开始给大家讲解。

他说:“克隆技术啊,就像是一个神奇的魔法,但这个魔法可不仅仅是为了好玩。

”他指着一张图片,上面是一只被克隆出来的羊,“比如说这只羊,通过克隆技术诞生,为农业领域带来了新的可能。

它有着和原母体一样优秀的基因,可能产更多的奶,或者有更好的肉质。

” 我在心里嘀咕着:“那要是都克隆这种优质的羊,其他普通的羊不就没‘饭碗’啦?”接着,他又提到了克隆技术在医学领域的应用。

“想象一下,如果能够克隆出人体器官,那些需要器官移植的病人不就有了更多的希望吗?不用再苦苦等待合适的捐赠者,也能大大提高手术的成功率。

”听到这儿,我不禁点了点头,心里觉得这确实是个能拯救生命的好法子。

不过,我也想到了一些让人担忧的问题。

要是有人利用克隆技术来克隆出一模一样的人,那岂不是乱套了?每个人都是独一无二的,如果到处都是克隆人,那这个世界的多样性不就被破坏了?而且,这还涉及到伦理道德的问题,比如克隆人的身份该怎么定义?他们有没有权利和正常人一样生活?想到这些,我感觉脑袋都要被这些复杂的问题给搅晕了。

克隆技术演讲

作为一项当代的新技术,正越来越受到人们的关注。

克隆技术对人类来说,仍是一把“双刃剑”。

以它为中心产生了截然相反的议论。

对它的认识,无论就技术革命而言,还是就人类伦理、道德等领域来说,都有着及为重要的意义。

克隆技术已展示出广阔的应用前景。

克隆技术与遗传育种在农业方面,人们利用“克隆”技术培育出大量具有抗旱、抗倒伏、抗病虫害的优质高产品种,大大提高了粮食产量。

在医学方面,人们正是通过“克隆”技术生产出治疗糖尿病的胰岛素、使侏儒症患者重新长高的生长激素和能抗多种病毒感染的干扰素。

克隆技术也对保护物珍稀、濒危物种来讲是一个福音。

例如,现在正在进行的猛犸象复活计划,研究人员曾通过西伯利亚冻土挖掘调查,获得了猛犸象的皮肤和肌肉组织。

但是这些组织的细胞核多半被冰的晶体所伤,无法利用。

后来研究团队开发出了一项新技术。

只要解冻的组织里2%到3%的细胞核未受损,应用新技术就可以把它们完好地提取出来。

2011年夏天这个团队从俄罗斯获得品质更好的猛犸象组织。

向日本全国的动物园请求在母象死亡时提供制作克隆胚胎所必需的卵子的工作已经完成。

一旦猛犸象的克隆胚胎培育成功,研究人员将很快给非洲象实施克隆胚胎移植手术。

如果有了完整的细胞核,接下来就是要找到匹配的卵细胞。

可以在现代动物中找猛犸象血缘的近亲,比如非洲象。

现在面临的问题就是为猛犸象找到合适的代孕妈妈,但借腹怀胎有难以控制排斥反应,猛犸象胚胎可能在还没有形成器官前就被消灭掉。

这是一次大胆的挑战,如果成功,将把生物技术向前推进一大步。

但克隆违背了伦理学的自主原则,比如说:某对夫妇在事故中失去了独生子,于是便通过克隆再制造一个孩子,其身体中的绝大部分基因是先前那个孩子的基因的复制。

这样尽管父母在一定程度上满足了某种欲望,但这整个行为方式对于被复制的孩子而言却意味着一种外来的决定,它将本属于这个孩子的偶然性的那部分自由剥夺了,而人一个最重要的特性,就体现在不可重复的独特性上。

克隆是指生物体通过体细胞进行的无性繁殖,以及由无性繁殖形成的基因型完全相同的后代个体组成的种群。

这样尽管父母在一定程度上满足了某种欲望,但这整个行为方式对于被复制的孩子而言却意味着一种外来的决定,它将本属于这个孩子的偶然性的那部分自由剥夺了,而人一个最重要的特性,就体现在不可重复的独特性上。

人的一个特殊的优先权就在于,每个人都有其自身的不可重复的特性。

上述的那对夫妇因为太喜欢第一个孩子,就不生第二个孩子,生出的第二个孩子可能与第一个孩子的外形都不太一样,而克隆出来的却与第一个孩子没有太大差别,等于是让他“新生了”。

可见第二个孩子完全是为了服从于父母的某种意图,作为父母的一个工具,父母通过他想起他们失去的那个孩子。

被克隆者作为人应享有的独特性便被剥夺了,他的不必非要有一个与别人同体同貌的自由,便被粗暴地践踏了。

也许未来的一天,当克隆技术变得成熟的时候,设想我们的世界将会变得怎样?这是个极端诱惑人的话题。

可以想象,也许,灭绝的动物将会奇迹般的复生,稀有动植物不再稀少,天生的残疾可以应用克隆器官的以弥补,意外的伤残得以健康的修复,医学迈进一个新台阶,农牧业上新的优良品种得到大面积推广和繁殖……也许,克隆人真的问世,成为我们移居星球征服宇宙的开拓者,跨越时间和空间的限制,克隆人利用宇宙光源和其他放射线合成能量和动能,成为人类永恒的扩荒者,代替我们到别的星球上取样和拍摄,带来一个个一想不到的神话传说……
刀,可以用来杀人,也可以用来救人,关键看它掌握在什么人手中。

克隆是一柄双刃剑,善良的人们可以利用它来为人类服务,为人类造福。

而邪恶的人们却能用它来危害人类的生存。

任何科学技术的发展,都有利有弊,只要人类正确运用克隆技术,那么它一定会有益于人类。

如果我们只看到它的弊端,而畏缩不前,那么人类社会就不会有发展,也不会有进步。

我们不能因噎废食,因为那样只能使人类固步自封,这就是我们想看到的结果吗?我坚信,只要能正确对待克隆技术,那么人类一定会从中受益匪浅。
