A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. They

A plasmid preparation is a method of DNA extraction and purification for plasmid DNA. It is an important step in many molecular biology experiments and

A tumour inducing (Ti) plasmid is a plasmid found in pathogenic species of Agrobacterium sensu lato, including A. tumefaciens, Rhizobium rhizogenes, A

cryptic plasmid is a plasmid that doesn't appear to provide any clear advantage to its host, yet still persists in bacterial populations. These plasmids appear

the plasmid copy number is the number of copies of a given plasmid in a cell. To ensure survival and thus the continued propagation of the plasmid, they

The F-plasmid (first named F by one of its discoverers Esther Lederberg；also called the sex factor in E. coli，the F sex factor, the fertility factor,

Plasmid-mediated resistance is the transfer of antibiotic resistance genes which are carried on plasmids. Plasmids possess mechanisms that ensure their

conjugation where a conjugative plasmid present in one bacterial strain assists the transfer of a mobilizable plasmid present in a second bacterial strain

bacterium with a conjugative plasmid (for example, the F-factor) integrated into its chromosomal DNA. The integration of the plasmid into the cell's chromosome

transmission of virulence. It often involves temperate bacteriophages and plasmids. Genes responsible for antibiotic resistance in one species of bacteria
