ブルーホワイトセレクションの問題です。 最初から分からないので、教えてください。 また、この問題がどこ大?何年度のセンター?か、分かれば教えてください(分かればでいいです)

図2に示した目的の遺伝子をプラスミドに組み込む操作を行った。目的の遺伝子 は塩基配列Iと塩基配列Iではさまれている。また図3に示した大陽菌のプラスミ ドは、B-ガラクトシダーゼ遺伝子と抗生物質Aの耐性遺伝子をもち、B-ガラクト シダーゼ遺伝子の中に塩基配列目をもつ。 塩配列1~Ⅲには, 制限酵素Bamll1. HindI, EcoRVが認識する配列がある。 それぞれの矢印は転写の方向である。 同一の塩基配男をもつ DNA 派片を得るための操作をクローニングといい。 PCR 法や、遺伝子組換えを利用する方法がある。 PCR法は目的の DNA を DNAポリメ ラーゼを用いて試験管内で増幅させる方法である。 遺伝子組換えを利用する方法は、 まず目的の遺伝子を含む DNA と大腸菌のプラスミドを、 同じ制限酵素で処理する。 目的の遺伝子を含む DNA の切断面とプラスミドの切断面は1本鎖部分の塩基どう しが相補的に水素結合するので、 DNA リガーゼを用いてヌクレオチド鎮どうしの 切れ目をつなぎ合わせ、目的の遺伝子をプラスミドに組み込むことができる(図1)。 こうしてつくられた組換えプラスミドを大腸菌に導入する。 この大腸直を培養すれ ば、大陽菌の増殖とともにプラスミドも増え、 目的とする DNA を大量に得ること 抗生物質Aの 耐性遺伝子 プロモーター 目的の遺伝子 一塩基配列 amHI Hind ECORV BamHI FroRVBamHI ベクター く 塩基配列1 塩基配列I ができる。 図 3 図 2 目的の遺伝子 GAATTC CTTAAG GAATTC DNA GAAT TAC CTTAAG 染色体 DNA 制限酵素の切断部分 大腸菌 AAT。 TTA。 プラスミドー 目的遺伝子からつく られるタンパク質の かたまり 図 1 DNAリガーゼ>
