1. 克隆技术与遗传育种 Cloning technology and genetic breeding
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。 In agriculture, the use of "cloning" technology has created a large number of drought and lodging resistance, high-quality high-yielding pest resistant varieties, greatly increased food production. 在这方面我国已迈入世界最先进的前列。 In this regard we have entered the forefront of the world's most advanced.
2. 克隆技术与濒危生物保护 Cloning technology and Endangered Wildlife
克隆技术对保护物种特别是珍稀、濒危物种来讲是一个福音,具有很大的应用前景。 Cloning technology, especially the protection of rare species, endangered species is a good news is, has great application prospect. 从生物学的角度看,这也是克隆技术最有价值的地方之一。 From the biological point of view, cloning is also one of the most valuable.
3. 克隆技术与医学 Cloning technology and medicine
在当代,医生几乎能在所有人类器官和组织上施行移植手术。 In modern times, doctors in almost all human organs and tissues on the purposes of transplantation. 但就科学技术而言,器官移植中的排斥反应仍是最为头痛的事。 However, in terms of science and technology, organ transplantation rejection remains the most headaches. 排斥反应的原因是组织不配型导致相容性差。 The reasons for rejection is a result-based organizations do not deserve poor compatibility. 如果把“克隆人”的器官提供给“原版人”,作器官移植之用,则绝对没有排斥反应之虑,因为二者基因相配,组织也相配。 If the "human cloning" of organs available to the "original people" for use in organ transplants, the rejection of no concern, because the two genes match, match organizations. 问题是,利用“克隆人”作为器官供体合不合乎人道? The problem is that the use of "human cloning" as the organ donor is not combined with humanity? 是否合法? Legal? 经济是否合算? Economy is cost-effective?
克隆技术还可用来大量繁殖有价值的基因,例如,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挠素,等等。 Cloning technology can also be used to the large population of valuable genes, for example, in medicine, it is through the "cloning" technology to produce insulin to treat diabetes, dwarfism patients so long to re-growth and high resistance to multiple virus infection Su-torsion of the stem, and so on.
4. 生长周期短,遗传性状稳定 Short growth cycle, the stability of genetic traits
5 克隆技术可解除那些不能成为母亲的女性的痛苦。 5 cloning technology are able to remove those who can not become a mother, the suffering of women.
6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。 6 cloning experiment has promoted the implementation of the development of genetics, in order to "create" can be transplanted into the human body opens up the prospect of animal organs.
7克隆技术也可用于检测胎儿的遗传缺陷。 7 cloning technology can also be used to detect fetal genetic defects. 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。 Cloning of the fertilized eggs for the detection of a variety of genetic diseases, cloning of embryos and the developing fetus in utero is identical to genetic characteristics.
8 克隆技术可用于治疗神经系统的损伤。 8 cloning technology can be used for the treatment of nervous system damage. 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。 Adults, there is no regeneration of nerve tissue, but stem cells can repair the nervous system injury.
9 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。 9 In the in vitro fertilization and surgery, doctors often need to be a number of fertilized eggs implanted into the uterus to draw into the pregnancy stage of screening. 但许多女性只能提供一个卵子用于受精。 However, many women only have one egg for fertilization. 通过克隆可以很好地解决这一问题。 Through cloning can solve this problem. 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。 Cloning of the egg cell can become more than used for fertilization, which greatly improved the success rate of pregnancy.
植物的克隆
许多植物都有先天克隆的本领。例如,从一棵大柳树上剪下几根枝条插进土里,枝条就会长成一株株活泼可爱的小柳树;把马铃薯切成许多小块种进地里,就能收获许多新鲜的马铃薯;把仙人掌切成几块,每块落地不久就会生根,长成新的仙人掌……此外,一些植物可以通过压条或嫁接培育后代。凡此种种,都是植物的克隆。
Plant Cloning
Many plants have the innate ability to clone. For example, from the willow tree branches cut into several territories, the branches on the president into a lovely small willow; the potatoes and cut into many small pieces of land, will be able to harvest a number of fresh potatoes ; the cactus into a few, each floor will soon take root, grow into new cactus ... ... In addition, some plants by layering or grafting nurture future generations. All these are plants of the clone.
