菌种简介
大肠杆菌噬菌体,是指寄生在大肠杆菌内的一种噬菌体,属于细胞病毒的一种。噬菌体还有一个特点就是具有专一性,一种噬菌体只在一种细菌中生活,而不能在另一种细菌中生活,人噬菌体是一种大肠杆菌的温和噬菌体,它是遗传工程中极好的载体分子,就是担当把动物的基因搬运进大肠杆菌细胞的搬运工角色。
菌种繁殖特点
繁殖过程可以分为吸附、侵入、复制、合成与释放4步。
(1)吸附。噬菌体以它的尾部末端高度特异性地吸附到敏感细胞表面上某一特定的位点,如细胞壁、鞭毛或纤毛。
(2)侵入。将自身的遗传物质(DNA)注入宿主细胞内。
(3)复制与合成。指噬菌体DNA和蛋白质外壳的复制。噬菌体DNA进入宿主细胞后,立即引起宿主的代谢改变,宿主细胞内的核酸不能按自身的遗传特性复制和合成蛋白质,而由噬菌体核酸所携带的遗传信息控制,借用宿主细胞的合成机构及酶等复制核酸,进而合成噬菌体的蛋白质。核酸和蛋白质装配合成新的噬菌体。
(4)释放。噬菌体粒子成熟后,噬菌体的水解酶水解宿主细胞而使宿主细胞裂解,噬菌体被释放出来。
大肠杆菌噬菌体并不会引起大肠杆菌所导致的一切病症。
