科普專欄–薯不揀單 - 三十秒科學–攻擊細菌的病毒

有能力消滅細菌的病毒，我們會稱之為Bacteriophage，又或者是Phage。458Please respect copyright.ＰＥＮＡＮＡL9u8BqL7ai

科學家發現，某特定品種Bacteriophage的DNA其英文字母的組合是由Z、T、C、G組成，常見的A被轉換成為Z。458Please respect copyright.ＰＥＮＡＮＡEjhpz1xYeC

(圖3)從圖中可見，Bacteriophage的ZT組合比AT組合多出一道Hydrogen Bond連繫。458Please respect copyright.ＰＥＮＡＮＡs5ZqcBfY7o

細菌對抗外敵的其中一道手段就是切斷外來入侵者的DNA，而基於Bacteriophage擁有與別不同的DNA，細菌們辨認A的蛋白酶沒能夠辨認Bacteriophage的Z，因此亦少了一道手段對抗Bacteriophage的入侵。458Please respect copyright.ＰＥＮＡＮＡtfMBdYVoFl

情形就像是男扮女裝的變態佬走進女廁一樣，透過改變自身的外貌來企圖掩菌耳目。458Please respect copyright.ＰＥＮＡＮＡL990WgIo5d
