填空题

阅读下列材料,回答问题:

材料一:俄罗斯科学院理论与实验生物物理研究所的科研人员,在分析了老鼠单细胞胚胎细胞核移植前后钾离子浓度的变化后发现,针对卵细胞进行的任何外在行为,必将破坏它的生物化学平衡,导致胚胎细胞正常发育进程的改变。因此,专家指出,这一实验成果有助于解释大量克隆动物出现不正常的原因。细胞核移植是现代生物技术中常见的现象:克隆、细胞核与细胞质相互作用、人工授精等,都要对卵细胞施加外在的作用。这种外在行为是否影响未来胚胎细胞的发育与成长?

材料二:在当代,医生几乎都能在所有人类器官和组织上实行移植手术。但就科学技术而言,器官移植中的排斥反应仍是最为头疼的事,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。问题是,利用“克隆人”作为器官供体合不合乎人道?是否合法?经济是否合算?克隆技术还可以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抗多种病毒感染的干扰素等。

(1)根据材料一,可得出大量克隆动物出现不正常的原因可能是______。

(2)尽管克隆动物在实际生活中还没有实际用途,但克隆技术在医学上却有巨大潜力,表现在_______。

(3)克隆技术作为现代生物技术和试管婴儿技术相比较,前者属于_______生殖,后者属于______生殖。

(4)器官移植中排斥反应仍是最为头痛的事,原因是_______。

(5)除了通过克隆技术生产人的胰岛素、生长激素和能抗多种病毒感染的干扰素外,还可以采用_______方法生产。

(6)英国罗斯林研究所的一项研究显示,利用克隆技术根本无法培育出完全相同的个体,究其原因,除了发育过程中的环境因素的影响外,还可能有________等原因(至少写出两个)。
