克隆的坏处英语?反对者言之凿凿:“克隆人”的出现将对现有社会的家庭结构、伦理体系造成巨大冲击;会成为恐怖主义分子犯罪的工具;制造大量基因结构完全相同的“克隆人”可能诱发新型疾病的广泛传播;就目前技术而言,无法保证“克隆”的安全性,可能出现流产、早产、死胎、畸形等不良结果等等。那么,克隆的坏处英语?一起来了解一下吧。
Cloning technology, a method of creating identical biological entities, has the potential to revolutionize various fields such as medication production, genetic research, and conservation efforts. However, its application is not without controversy and challenges.
Firstly, cloning technology holds the promise of addressing certain health issues. Scientists can utilize this method to produce identical cells for therapeutic purposes. Furthermore, it enables comprehensive genetic studies, enhancing our understanding of human body structures and functions.
Yet, several concerns arise with the use of cloning technology. Ethical and moral dilemmas are prominent among them. The ability to clone genes could potentially undermine the traditional family structure and create complex relationships. Moreover, cloning could lead to genetic pollution and ecological disruption, as cloned species might compete with their wild counterparts, upsetting the natural balance.
In conclusion, cloning technology presents both advantages and disadvantages. Its implementation requires a careful consideration of various factors, including ethical, moral, ecological, and economic implications. Only through a comprehensive analysis can we effectively harness this technology for the betterment of society.
克隆是英文clone的音译,简单讲就是一种人工诱导的无性繁殖方式。但克隆与无性繁殖是不同的。无性繁殖是指不经过雌雄两性生殖细胞的结合、只由一个生物体产生后代的生殖方式,常见的有孢子生殖、出芽生殖和分裂生殖。由植物的根、茎、叶等经过压条或嫁接等方式产生新个体也叫无性繁殖。绵羊、猴子和牛等动物没有人工操作是不能进行无性繁殖的。科学家把人工遗传操作动物繁殖的过程叫克隆,这门生物技术叫克隆技术。
克隆的基本过程是先将含有遗传物质的供体细胞的核移植到去除了细胞核的卵细胞中,利用微电流刺激等使两者融合为一体,然后促使这一新细胞分裂繁殖发育成胚胎,当胚胎发育到一定程度后,再被植入动物子宫中使动物怀孕,便可产下与提供细胞者基因相同的动物。这一过程中如果对供体细胞进行基因改造,那么无性繁殖的动物后代基因就会发生相同的变化。
1997年2月22日,英国罗斯林研究所的科学家维尔穆特等人宣布用体细胞克隆绵羊获得成功,在世界上引起巨大震动。一时间,克隆绵羊“多利”成为动物界最耀眼的“明星”,其“咩咩”的叫声迅速响遍全球。
“克隆”是英文单词“Clone”的音译,其本身的含义是无性繁殖,即由同一个祖先细胞分裂繁殖而形成的纯细胞系,该细胞系中每个细胞的基因彼此相同。
对克隆人的法律身份难以界定,无法判断其父母,产生财产纠纷。
违反自然规律,引起疾病,违反宗教的教义
克隆人犯罪很难辨别是本人还是克隆人,其指纹都一样。
克隆人引起人口爆炸
人类是困扰许多道德问题的每一天。 With recent由于近来
announcement that a research facility in England had successfully cloned a sheep, many more questions arose.宣布在英国研究机构已成功地克隆了绵羊,还有更多的问题出现。 The overall question is , "To clone or not to clone?"总的问题是,“克隆还是不克隆?” Many groups worldwide, doctors, politicians, religious people, have been battling with this question.全世界,医生,政治家,宗教人士,已被许多团体作战这个问题。
Many doctors believe cloning is an advancement to help save more people's lives.许多医生认为克隆是一个进步,以帮助拯救更多人的生命。 Although specific organs or rare blood types have yet to be cloned and actually made available to the general medical community.虽然特定的器官或稀有血型尚未被克隆和实际提供给整个医疗界。
To clone or not to clone, is that the question? Advanced technology has already pushed human being to edges,such as the production of weapons of mass destruction,the destruction of Ozone by Freon ,and the application of clone.The heated deabte over whether cloning technique should be used in human reproduc-- tion must be considered as a serious issue. Clone, to a certain degree, is beneficial to mankind.Such disease as Parkinsons will possiblly be cured in the future in the hope of further applying of clone.However,the abuse of this technology will bring human being unthinkable destruction. Since the declaration of the death of Dolly,we are more conscious of the inefficient procedure of clone.Acorrding to "Dolly's false legacy",the incidence of death among fetuses and offspring produced by cloning is much higher than it is through natural reproduction--roughly 10 times as high as normal before birth and 3 times as high after birth.And even you may argue that this technology will be perfected in the future, i don't see there is any point in whole--being cloning. Many people consider this technology a promising one as to bring all human being to a new era in which all human reproduction will be accomplished by cloning.Thus scientists in some countries have already started their great plan to clone human.But let's think, what is the practical value in doing so?You may tell me that it can bring hope for those couples unable to have children because they might choose to have a copy of one of them rather than accept the gene intrusion from a doner.But imagine,if you have a child owning the same apperance as yours or your husband's, will you accept it without any uncomfort? Don't you think it is embarrassing?Or if this kind of human reproduction is allowed,terrorists may get hold of it and reproduce lots of "American Presidents".Don't you agree that these presidents might bring the world much more chaoes?Besides these terrible aspects,the cloning of whole--being may destroy the diversity of people of the globe. Of course, there still remains much more disadvantages of the application of cloning reproduction of human being and animals. We should be extremely cautious of what we do and thus remember we will sure be respondible for all the results created by ourselves!!! So how do u think about it?Collected by www•ii63.com
以上就是克隆的坏处英语的全部内容,If a young child is killed in a car accident, a grief stricken mother could have him cloned.如果是一个年轻的孩子在一场车祸中丧生,1悲痛的母亲可以拥有他克隆的。 By doing this, she did not let herself rightly heal.通过这样做,她没有让自己正确地愈合。
