They are most commonly found in bacteria as small, circular, double-stranded DNA molecules; however, plasmids are sometimes present in archaea and eukaryotic organisms. In nature, plasmids often carry genes that may benefit the survival of the organism, for example antibiotic resistance.he normal number of copies of plasmid that may be found in a single cell is called the copy number, and is determined by how the replication initiation is regulated and the size of the molecule. Larger plasmids tend to have lower copy number.
Types of Plasmids. The combination of elements often determines the type of plasmid. Below are some common plasmid types: 1  Cloning Plasmids-Used to facilitate the cloning of DNA fragments. 2  Cloning vectors tend to be very simple, often containing only a bacterial resistance gene, origin and MCS.3  They are small and optimized to help in the initial cloning of a DNA fragment.ypes of Plasmids.
