Griffith y la transformación bacteriana. En 1928 se desarrolló un experimento que, en ese momento, pareció de poca importancia para el campo de la genética. Frederick Griffith (1881-1941), un bacteriólogo de salud pública de Inglaterra, estaba estudiando la posibilidad de desarrollar vacunas contra Streptococcus pneumoniae, un tipo de ...
Frederick Griffith (1877–1941) was a British bacteriologist whose focus was the epidemiology and pathology of bacterial pneumonia. In January 1928 he reported what is now known as Griffith's Experiment, the first widely accepted demonstrations of bacterial transformation, whereby a bacterium distinctly changes its form and function.
格里菲斯實驗（Griffith's experiment），又稱格里菲斯轉型實驗，是由弗雷德里克·格里菲斯（Frederick Griffith）在1928年利用肺炎鏈球菌與老鼠所進行的一系列生物學 實驗。實驗結果顯示，細菌的遺傳訊息，會因為轉型（或稱轉化）作用而發生改變。
Flexi Says: Many scientists contributed to the identification of DNA as the genetic material. In the 1920s, Frederick Griffith made an important discovery. He was studying two different strains of a bacterium, called R (rough) strain and S (smooth) strain. He injected the two strains into mice.

弗雷德里克·格里菲斯（Frederick Griffith，1877– 1941年）是英国细菌学家，其重点是细菌性肺炎的流行病学和病理学。 1928年1月，他报导了现在被称为格里菲斯（Griffith）的实验，这是第一个广泛接受的细菌转化的证明，从而明显改变其形式和功能。
Transformation is a molecular biology mechanism via which foreign and exogenous genetic material is taken up by a cell and incorporated into its own genome. This phenomenon was first described and discovered by British bacteriologist, Frederick Griffith. The concept of transformation and the experiment that led to its discovery are described here.
