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.如果说格雷的第一张人体解剖图解开了人体结构之迷,奠定了近代医学的基础,但同时也给人类带来很大的困惑.
女娲造人时,上天便赐于我们眼睛.有一天人们用它第一次在水中惊喜地看见了自己的倒影,而后人们通过镜子看自己,直到现在,人们又通过基因这一特殊的镜子,以一种全新的形式审视自己,由此审视世界.
我们欣喜地看到了基因研究利用的广阔前景.随着转基技术的运用,水仙的基因已被植入水稻,使之含铁量明显的增高;随着人们对基因的了解,克隆技术应运而生;第一只克隆羊多利活生生地站在了人们面前;随着克隆技术的发展,人类的器官可以被克隆,有望用新器官接替我们已老损的器官.......如此种种让人类似乎已可充当第二个上帝,或者说第二个女娲了.有人说上帝总是一手拿着答案,一手拿着问号.
克隆是英语单词clone的音译,clone源于希腊文klon,原意是细苗或嫩枝以无性繁殖或者营养繁殖的方式培育植物,随着时间的推移,克隆的内涵已经扩大了,只要是由1个细胞获得2个以上的细胞,细胞群或生物体,由一个亲本序列产生的DNA的序列,就是克隆.
克隆就如一把双刃剑.
每当春暖花开的时候,喜欢弄草的人便会做植物扦插;一种外观像苹果而味道似梨的水果—苹果梨,就是采用果树嫁接法培养而成的,扦插和嫁接实质上也是克隆.也是对人类的好处.克隆人体器官对医学发展也有很大促进作用,更是对身患癌症或残疾人的一个福音.
克隆人与亲本间的辈分关系,克隆人该是作为父辈,子辈或同一辈分或者是其它,这与我们平常所遵循的长幼有分起了矛盾,也会混乱各种社会人际关系.
克隆人是对人的不种不尊重表现.克隆人,就不只是件复制品.倘若人可以随意克隆,那就是就每个人都拥有无数次生命.此时再讲生命的价值已毫无意义了.这是否也意味着生命可以任意践踏,人格可以任意伤害 这又与我们平时所强调的尊重每个人的生命.生命只有一次又从何谈起 一个人,如果连对自已生命的自主权都没有,那他的生存意义何在
克隆人会给野心家和不法分子有利可乘.我们不能不考虑到有可能克隆人将引发一声战争.野心家利用克隆人征服全球,这似乎在科幻小说中才能见到.但现实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.
我们应该理智地看待克隆,将它变为对人类有利的科学技术而非人类走向灭亡的武器.
