在现代替物技术的微观世界中,限制性核酸内切酶是基因工程的关键工具之一,而 ApaI 便是其中一位“精细切割手”。它以其高度的特异性和精细的切割能力,在基因工程、分子生物学研究以及遗传学等领域发挥着重要作用。ApaI 的识别序列是“GGG^CCC”,这一序列在基因组中相对罕见,使得 ApaI 能够在特定位置进行切割。它会在识别到该序列后,在“^”标记的位置将 DNA 链切断,产生黏性末端。这种切割方式使得 ApaI 在基因克隆和重组 DNA 构建中具有独特的优势。在基因工程中,ApaI 的应用极为广。科学家可以利用它将目标基因从复杂的基因组中精细地分离出来,再通过 DNA 连接酶将切割后的基因片...
