【-】 すべての細胞が同じ一定の速度で均一に増殖し ているある動物の培養細胞集団から、 ある個数の細胞 を採取して,細胞当たりのDNA量を測定したところ, 図に示す結果を得た。 この培養細胞集団の細胞周期は 24時間であり,図中のB群の細胞数の合計が1500個, M期の細胞数が300個であることがわかっている。 (1)にな A 100個の培養細胞から実験に用いた6000個の培養細 胞を得るためには、何日間培養する必要があるか。 関係ない。 (2) 細胞周期は, Gi期・S期・G2期・ M期の4つに分ける ことができる。図中のA群~C群には, それぞれ細胞周期のどの時期の細胞が含まれているか。 それぞれあてはまるものをすべて答えよ。 細胞周期の各時期に要する時間の長さは、その時期の細胞数に比例しているとすると, G2期に 要する時間は何時間か。 S期の細胞数 全細胞数 (1) S期の時間 細胞周期 S期の時間 = =24× 1500 6000 6 細胞数(個) 3000円 11 ¥2000円 11 1000 - SAA a Sell 12 - 15,00 .
