翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Directed mutagenesis ： ウィキペディア英語版 Directed mutagenesis Directed mutagenesis, also known as directed mutation, is a hypothesis proposing that organisms can respond to environmental stresses through directing mutations to certain genes or areas of the genome. ==History== The Russian ichthyologist Lev Berg proposed directed mass mutations as the main mechanism for evolution in his anti-Darwinian book ''Nomogenesis; or, Evolution Determined by Law'' (1922). Early studies of "directed mutation" were performed by German geneticists. Richard Goldschmidt in 1929 due to his experiments on drosophila through exposure to elevated temperatures had claimed to have produced evidence for directed mutation. Viktor Jollos (1887-1941) in the 1930s had also carried out experiments on drosophila and written that his results had confirmed Goldschmidt's work which was evidence for direct mutation in contrast to natural selection. However later American geneticists were unable to replicate these experiments. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Directed mutagenesis」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
