49.(5分)通過基因突變產(chǎn)生了營養(yǎng)缺陷型菌株,由于營養(yǎng)缺陷型菌株喪失了合成某一物質(zhì),例如氨基酸、嘌呤、嘧啶、維生素等的能力,不能在基本培養(yǎng)基中生長,必須在基本培養(yǎng)基中補充某些物質(zhì)才能生長。下圖簡要表明了科學研究者用紫外線處理野生型啤酒酵母菌單倍體獲得其營養(yǎng)缺陷型菌株的方法。

根據(jù)以上敘述,完成以下內(nèi)容。

(1)啤酒酵母菌產(chǎn)生能量的場所是              。

(2)圖中酵母菌應選其生長曲線中的哪一時期的菌株最理想?為什么要用單倍體的酵母菌?

(3)紫外線的作用是             。

(4)現(xiàn)有5種單基因突變型大腸桿菌1、2、3、4、5,它們不能合成生長所必需的物質(zhì)G。A、B、C、D、E都是合成G物質(zhì)的必需中間產(chǎn)物,但不知這些物質(zhì)合成的順序,于是在培養(yǎng)基中分別加入這幾種物質(zhì)并分析了這幾種物質(zhì)對各種突變體生長的影響。結果如下(表中“+”表示生長,“-”表示不生長):
