37.(15分)[现代生物科技专题]下图分别表示的是基因的结构示意图和科学家通过基因工程培育抗虫棉时,从苏云金芽孢杆菌中提取抗虫基因开始,到“放入”棉花细胞中与棉花的DNA分子结合起来而发挥作用的过程示意图。请回答下列有关问题:

(1)图C中的目的基因是从图A和图B中哪一个基因提取的?        ,说明理由                                     

(2)图C中①过程需要工具酶是                   

(3)图C中的III是导入目的基因的受体细胞,经培养、筛选获得一株有抗虫特性的转基因植株。经分析,该植株含有一个携带目的基因的DNA片段,因此可以把它看作是杂合子。理论上该转基因植株自交F1代中仍具有抗虫特性的植株占植株总数的      ,原因是                           

(4)科学家认为,此种“转基因的抗虫棉”种植后,也可能出现以前从没有过的不抗虫植株,此植株形成的原因最可能是_________________。

(5)如果在长期种植过程中,抗虫棉逐渐丧失抗虫特性,用现代进化理论解释原因:
