Detailed explanation-1: -Plasmids are self-replicating extrachromosomal DNA molecules found in Gram-negative and Gram-positive bacteria as well as in some yeast and other fungi. Although most of them are covalently closed circular double-stranded DNA molecules, recently linear plasmids have been isolated from different bacteria.

Detailed explanation-2: -Plasmids are extrachromosomal DNA molecules that can potentially be transferred horizontally as well as vertically in bacterial lineages. Plasmids have been shown to code for numerous bacterial phenotypes, the most concerning of which is resistance to commonly used antibiotics.

Detailed explanation-3: -Plasmids. Plasmids are replicons that are maintained as discrete, extrachromosomal genetic elements in bacteria. They are usually much smaller than the bacterial chromosome, varying from less than 5 to more than several hundred kbp, though plasmids as large as 2 Mbp occur in some bacteria.

Detailed explanation-4: -Plasmids are extra chromosomal genetic element found in many bacteria. Plasmids are closed circles of double stranded DNA that can exists and replicate independently of the chromosome. Plasmids provide genetic instruction for certain cell activities (e.g. resistance of antibiotic drugs).

Detailed explanation-5: -A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. They are most commonly found as small circular, double-stranded DNA molecules in bacteria; however, plasmids are sometimes present in archaea and eukaryotic organisms.
