A plasmid is a small, circular, double-stranded DNA molecule that is physically separated from chromosomal DNA and can replicate independently. Plasmids are most commonly found in bacteria, but can also be present in archaea and eukaryotic organisms. 

Plasmids are used for a number of applications, including: 
Transfection, Sequencing, Screening clones, Restriction digestion, Cloning, PCR. 
 

There are several types of plasmids, including: Resistance plasmids, Virulence plasmids, Degradative plasmids, Col plasmids, Fertility F plasmids. 

Here are some examples of plasmids:
Ti plasmid: A virulence plasmid found in the plant pathogen Agrobacterium tumefaciens. It causes crown gall disease in plants.
Col plasmid: Also known as Bacteriocins, this plasmid produces colicins or bacteriocins. These proteins defend the host bacterium by killing other harmful bacterial strains.
Degradative plasmid: This plasmid contains genes for special enzymes that break down specific compounds. These compounds include camphor, xylene, toluene, and salicylic acid.
