  1. 遺傳物質DNA的發現 • 1928 格里夫茲 (Griffith)肺炎雙球菌轉形試驗 • 1942 艾佛瑞(Avery)研究格里夫茲轉形的物質為何? • 1952 赫希-卻斯 (Hershey-Chase)以放射線標示噬菌體的蛋白質(S35)和DNA(P32),感染大腸桿菌的實驗 • 1953 華生與克立克(Watson、Crick)發現DNA雙螺旋結構

  5. 遺傳中心法則 • DNA→RNA→蛋白質 • mRNA的剪切由核內的小分子RNA (snRNA)和snRNA蛋白質複合體(snRNPs)及SR蛋白質參與,這些分子形成剪接體結構(splicesome) • 反轉錄酶的發現顛覆了此中心法則 • 1970 Howard Termin和David Baltimore 發現 (1975 Nobel) • 一些RNA病毒能利用反轉錄酶將它們的遺傳物質(RNA)反轉錄為DNA
