WebMay 23, 2024 · Properties/Characteristics of bacterial plasmids: Physical properties: Plasmid is a double-stranded circular and supercoiled DNA. Within a cell, it can exist autonomously. It can replicate independently of the bacterial chromosome. It has a molecular weight of 10 6 -10 8 which may encode from 40-50 genes. WebInitial schemes were based on the ability of a plasmid to inhibit F fertility, but due to certain limitations, these methods were superseded by incompatibility or Inc typing. Inc typing classifies plasmids by their ability to stably coexist with other plasmids in the same bacterial strain, a trait that is dependent on their replication machinery.
