49.(5分)通过基因突变产生了营养缺陷型菌株，由于营养缺陷型菌株丧失了合成某一物质，例如氨基酸、嘌呤、嘧啶、维生素等的能力，不能在基本培养基中生长，必须在基本培养基中补充某些物质才能生长。下图简要表明了科学研究者用紫外线处理野生型啤酒酵母菌单倍体获得其营养缺陷型菌株的方法。

根据以上叙述，完成以下内容。

(1)啤酒酵母菌产生能量的场所是　　　　 　　　　　　　　　。

(2)图中酵母菌应选其生长曲线中的哪一时期的菌株最理想？为什么要用单倍体的酵母菌？

(3)紫外线的作用是　　　　　　　　　　　　 。

(4)现有5种单基因突变型大肠杆菌1、2、3、4、5，它们不能合成生长所必需的物质G。A、B、C、D、E都是合成G物质的必需中间产物，但不知这些物质合成的顺序，于是在培养基中分别加入这几种物质并分析了这几种物质对各种突变体生长的影响。结果如下(表中“+”表示生长，“-”表示不生长)：
