copy mutantとは 意味・読み方・使い方

The mutant strain having increased content of the rRNA is obtained by subjecting a yeast from which an RRN10 gene is deleted, preferably, the yeast from which an FOB1 gene is deleted, and which has an increased copy number of the rDNA by possessing a splitting chromosome originated from a chromosome having an rDNA cluster to mutation treatment, and selecting a mutant strain growing more than the case before the mutation treatment.例文帳に追加

RRN１０遺伝子を欠失した酵母、好ましくは、さらに、ＦＯＢ１遺伝子を欠失し、かつ、ｒＤＮＡクラスターを有する染色体に由来する分断染色体を保持することによりｒＤＮＡコピー数が増加した酵母を変異処理し、変異処理前よりも生育が向上した変異株を選択し、ｒＲＮＡ含量が増加した変異株を取得する。 - 特許庁
