In 1928,Frederick Griffithdiscovered the phenomenon of transformation (see Griffith's experiment ): dead bacteria could transfer genetic material to "transform" other still-living bacteria. 1928年,弗雷德里克·格里菲斯发现了转化 现象(参见格里菲斯實驗 ) : 死亡的细菌可以将遗传物质"转化"到其他依然活着的细菌...
Frederick Griffith(born October 3, 1877, Eccleston, Lancashire, England—died 1941, London) was a British bacteriologist whose 1928 experiment with bacterium was the first to reveal the “transforming principle,” which led to the discovery thatDNAacts as the carrier ofgeneticinformation. ...
格里菲斯实验是由弗雷德里克·格里菲斯(Frederick Griffith)在1928年利用肺炎链球菌与老鼠所进行的一系列生物学实验。实验结果显示,细菌的遗传讯息,会因为转型(或称转化)作用而发生改变。实验与原理 此实验是利用两个不同的肺炎链球菌(可感染老鼠)品系,一种是III-S型(平滑型,有毒性),另一种是II-R型(粗糙...
