1.简介

基础研究通过推进人类认知进而可能解决人类面临的问题,而人类面临的问题通过刺激科学研究也可能推进人类认知。不同研究途径的科学前沿间的意外交汇往往使我们对问题的认识达到质的飞跃。本次课程讨论的基因物质基础的研究历程,即对遗传科学问题的好奇与对肺炎医疗问题的需求合力推动人类认知的典型实例。Friedrich Miescher、Albrecht Kossel、Phoebus Levene、Torbjörn Caspersson等从生物化学角度分析染色体的化学成分。Gregor Mendel、Walther Flemming、Theodor Boveri、Thomas Morgan等着力于染色体生物功能的研究,并由此诞生与发展了遗传学。而对肺炎致病性细菌流行病学研究中,Fred Griffith、Oswald Avery、Colin MacLeod、Maclyn McCarty等逐步揭示DNA为遗传信息的载体。以上异途同归的研究刺激了Rosalind Franklin、Maurice Wilkins、James Watson、Francis Crick对DNA结构的解析,分子生物学也随之诞生。
