原本題目:

50 α-Amanitin對下列何酶不產生抑制作用？ (A)RNA polymerase I (B)RNA polymerase II (C)RNA polymerase III (D)RNA polymerase IV

修改成為

50 α-Amanitin對下列何酶不產生抑制作用？ (A)RNA polymerase I (B)RNA polymerase II (C)RNA polymerase III (D)RNA polymerase IV

答案應該AC都對
(這題感覺原本是想問對誰會產生抑制作用，所以答案才會是B)

alpha-Amanitin, a toxic substance from the mushroom Amanita phalloides, is a potent inhibitor of DNA-dependent RNA polymerase II (the nucleoplasmic form) from sea urchin, rat liver, and calf thymus. This compound exerts no effect on the activity of polymerase I (nucleolar form) or polymerase III (also nucleoplasmic).
