Plasmid Profile Typing and Plasmid Fingerprinting

Plasmids are extra-chromosomal molecules of deoxyribonucleic acid (DNA) capable of autonomous replication. Such molecules have been identified in many bacterial genera and usually exist as covalently closed circular (CCC) molecules. Plasmids

质粒 plasmid

质粒 plasmid 在细胞内整个世代稳定地传递给后代，但并不在染色体上而进行自主增殖的一类遗传因子的总称。该类因子的存在与否，对细胞的生存无关紧要。这个名词主要指细菌细胞内的因子，它们包括可在细胞间发生传递的F因子、 R因子、大肠杆菌素因子等。此外，还有各种本身不能传递的因子。在具有质粒细胞的后代中，有时会出现低频率的失去质粒的细菌。在质粒中，对那些能变成插入奇主染色体状态的特殊质粒，特称为附加体（episome）。
