基因转型(gene－transformation)
目的带有特定基因的质体在分子生物研究上，是一个很重要的工具，将质体送入细菌的过程称为基因转形，经由基因转型可使质体在细菌中大量复制，以备进一步研究。本实验将把你在前面转殖实验中cDNA和质体DNA的连结反应送入细菌。 你将从本实验学习如何进行基因转型作用。原理早在1970年左右，有人发现细菌经由冰冷

关于细菌细胞壁缺陷型的基本介绍
细菌细胞壁缺陷型（细菌L型） 细菌细胞壁的肽聚糖结构受到理化或生物因素的直接破坏或合成被抑制，这种细胞壁受损的细菌一般在普通环境中不能耐受菌体内的高渗透压而胀裂死亡。但在高渗环境下，它们仍可存活。 革兰阳性菌细胞壁缺失后， 原生质仅被一层细胞膜包住，称为原生质体（protoplast）；革兰阴性
