1.突變和基因重組產(chǎn)生了生物進(jìn)化的原始材料，現(xiàn)代生物技術(shù)也是利用這一點(diǎn)來(lái)改變生物遺傳性狀，以達(dá)到人們所期望的目的。下列有關(guān)敘述錯(cuò)誤的是　　　　　　 (　)

A.轉(zhuǎn)基因技術(shù)造成的變異，實(shí)質(zhì)上相當(dāng)于人為地基因重組，但卻導(dǎo)致了自然界沒(méi)有的定向變異的產(chǎn)生

B.體細(xì)胞雜交技術(shù)是人為造成染色體變異的方法，它打破了自然界生殖隔離的限制

C.人工誘變沒(méi)有改變突變的本質(zhì)，但卻因突變率的提高而實(shí)現(xiàn)了定向變異

解析：人工誘變的本質(zhì)是基因突變，可以提高突變率但不能控制突變方向。
