Detailed explanation-1: -A plasmid is a small circular DNA molecule found in bacteria and some other microscopic organisms. Plasmids are physically separate from chromosomal DNA and replicate independently.
Detailed explanation-2: -A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell’s chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance.
Detailed explanation-3: -Plasmids are extra-chromosomal small circular DNAs that are capable of replicating independently of the host, and are present throughout a variety of different microorganisms, most notably bacteria.
Detailed explanation-4: -Plasmids carry genes for replicating their DNA, transferring themselves from one host cell to another, and for a variety of phenotypes.
Detailed explanation-5: -Scientists can force bacteria to keep them. They are copied independently. They are circular. 25-Mar-2014
