额。打了我半小时字。希望对你有帮助!看内容也知道是手工翻译的哈!Unit 2 克隆:他将把我们引向何方?克隆一直与我们同在,而如今它还要坚持下去。这是一种用来生产与原型完全相同的动植物的方法。当园艺师从生长的植物上剪下枝条来培植新植物时,就会产生这种现象。这种现象也发生在动物身上,从同一个原生卵子产生性别和相貌相同的双胞胎也是克隆。实际上,这些都是自然克隆现象。克隆技术有2大用途。第一,园艺师一直用他生产大量的商用植物;第二,他在对新植物物种的研究以及对动物的医学研究方面都是很有价值。克隆植物简单,但是克隆动物就比较复杂了,是一项很难完成的任务,克隆哺乳动物的多次常识都失败了,但是,科学家的决心和耐心最终得到了回报,这就是1996年具有突破性的克隆羊“多莉”的诞生。它的程序如下图所示:一方面,整个科学界都在关注着首例成功的克隆动物多莉羊的成长,多莉看来是在正常的成长着,这很令人鼓舞。接着传来了多莉并重的坏消息。研究克隆的科学教发现多利得的病更容易发生在年老的羊身上。这让他们很沮丧。多莉总共只存活了六年半,这是它的原型羊寿命的一半。可悲的是,同样无法控制的命运也在影响着其他物种,如克隆鼠。科学家的脑海里产生的问题是:“这是不是所有的克隆动物的一个主要困难呢?这种现象会不会永远发生?如果改进程序。问题会不会解决?另一方面,多莉的出生引起了一阵强烈的反对,对,对媒体和公众的想象力也产生了巨大的影响。它引起了争议,因为他突然打开了人们的眼界,看到了有可能:用克隆技术来治疗重病,甚至是克隆出人类。尽管目前供克隆研究的人体细胞和胚胎还很难得到,但是报纸报道说,有些邪恶头目希望把自己克隆出来以实现他的野心。宗教领袖也提出了道德方面的问题。各国政府惶恐不安而且更加谨慎,有些政府开始改革司法制度,明令禁止进行克隆人类的研究。但是其他国家如中国和英国,现在还在继续收集克隆技术有可能提供妇幼的医疗救助的证据。然而,科学家们仍对克隆技术有助于人类还是有害于人类,以及克隆技术讲吧我们引向何处困惑内容来自www.07swz.com请勿采集。
