2008年诺贝尔化学奖授予了三位在研究绿色荧光蛋白(GFP)方面做出突出贡献的科学家。绿色荧光蛋白能在蓝光或紫外光的激发下发出荧光,这样借助GFP发出的荧光就可以跟踪蛋白质在细胞内部的移动情况,帮助推断蛋白质的功能。GFP基因可作为目的基因用于培育绿色荧光小鼠,下图表示培育绿色荧光小鼠的基本流程:
请根据上述材料回答下列问题:
(1)过程①必需用到的工具酶是 。
(2)过程②将基因表达载体导入小鼠受精卵时,采用最多也最有效的方法是 。然后还可以通过 技术来检测绿色荧光蛋白基因是否已导入成功。
(3)在进行过程④前,利用 技术可以获得数目更多且基因型相同的绿色荧光小鼠。
(4)GFP基因与目的基因一起构建到载体上不影响目的基因的表达,也不影响由目的基因控制合成的蛋白质的结构与功能,且对细胞无毒性作用,因此GFP基因可以运用作为基因表达载体上的 。
