I really really want to know!So thank you!

B咯,基因工程的用途就有一个是进行基因诊断,用的就是DNA分子杂交.
再问：为什么不是c
再答：抗原抗体结合是免疫的内容，与基因工程没一点关系
再问：可是基因工程里讲了啊
再答：题目是说基因工程，不会与抗原抗体有关，基因工程是DNA重组技术，必须是B
再问：那讲的分子水平和个体水平是什么啊
再答：分子水平是DNA,蛋白质之类的分子的操作，如基因工程，个体水平是从完整个体上来研究，如根据是都表现某一性状之类的。
再问：分子水平检测不是包括是否插入目的基因是否转录是否翻译有关吗，检验是否转录是否插入目的基因不是用DNA分子杂交嘛
再答：然后？
再问：不懂了啊
再问：就这个题嘛
再问：运用的是什么原理？那三条的那一条？
再答： DNA分子杂交，选B
再问：

再问：什么原理
再答： DNA杂交，诊断患者体内是否有该病毒
再答：我算懂你意思了，再看一遍题目吧，如果是抗原抗体结合，那就是说病毒已经表达其蛋白质，也就是病人已经患非典，那为何还要诊断？诊断的意思是判断其是否患病。
再问：诊断怎么会知道患没患病呢
再问：喔喔懂了懂了谢谢～

I really really want to know!So thank you!快 I really really want to know, I really want to know( ) I WANT TO KNOW WHAT YOU REALLY WANT I really miss you Really want to 是I really don't want you to know.还是 I don't really want you I really want to want you,do not know how the.Do I really fe I really miss you,want to embrace you...Do you know?I really I really want you to know that I really love you.
