传说古希腊人攻打特洛伊城时,将精兵藏在一个大木马肚子内,并诱使特洛伊人将木马拖入城中,夜间奇兵钻出木马,里应外合,攻陷了此城。“木马计”的典故就是这么来的。斯坦福大学科尔教授领导的小组,在研究中合成了一种环状的纳米级DNA(脱氧核糖核酸)分子,并用它充当“木马”,放入活的大肠杆菌细胞中。这种分子“木马”进入大肠杆菌细胞后能大量制造另外一种名为核酶的物质,并由后者在细菌内部发起“进攻”,关闭特定基 Legend has it that the ancient Greeks attacked Troy City, will be hidden in a large wooden trojan horse, and to induce Trojan dragged into the city of Trojans, rockets at night, drilled Trojans, which should be co-operative, captured the city. “Trojans” allusions is so come. A team led by Professor Cole at Stanford University synthesized a circular, nanoscale DNA molecule that was used as a “trojan” in live E. coli cells. This molecule “Trojan horse” into the E. coli cells can mass-produce another kind of material called ribozyme, and the latter in the bacteria initiated “offensive”, turn off specific base
