Unlike viruses, which encase their genetic material in a protective protein coat called a capsid, plasmids are 'naked' DNA and do not encode genes necessary to encase the genetic material for transfer to a new host however, some classes of plasmids encode the conjugative 'sex' pilus necessary for their own transfer. This host-to-host transfer of genetic material is one mechanism of horizontal gene transfer, and plasmids are considered part of the mobilome. Plasmids are transmitted from one bacterium to another (even of another species) mostly through conjugation. However, plasmids, like viruses, are not generally classified as life. Plasmids are considered replicons, units of DNA capable of replicating autonomously within a suitable host. Illustration of a bacterium showing chromosomal DNA and plasmids (Not to scale) Synthetic plasmids are available for procurement over the internet. In the laboratory, plasmids may be introduced into a cell via transformation. Artificial plasmids are widely used as vectors in molecular cloning, serving to drive the replication of recombinant DNA sequences within host organisms. While chromosomes are large and contain all the essential genetic information for living under normal conditions, plasmids are usually very small and contain only additional genes that may be useful in certain situations or conditions.

In nature, plasmids often carry genes that benefit the survival of the organism and confer selective advantage such as antibiotic resistance. of software packages that handle plasmid maps are ApE, Clone Manager, Gene Construction Kit, Geneious, Genome Compiler, LabGenius, Lasergene, MacVector. They are most commonly found as small circular, double-stranded DNA molecules in bacteria however, plasmids are sometimes present in archaea and eukaryotic organisms.

Track 5 shows the banding pattern for a 50:50 mix of the two plasmids (not the non equip-molar intensity of the variant bands) and track 6 shows the difference in band intensity when the mutant plasmid represents just one third of the molecules. In gel tracks 3 and 4 you can see the different banding patterns between pBR322 and pBR322+. (Note that by default MacVector only shows a maximum of 8 cuts per enzyme so we increased this to unlimited in the RE Picker to ensure the FspI sites were displayed). Finally we used File | New Agarose Gel to create an empty gel, then selected FspI sites from each of the four molecules and dragged them onto separate lanes in the agarose gel. Then we added a second copy of pBR322 into one of the EcoRI sites to create a molecule with two copies of pBR322 and one copy of pBR322+ (Hybrid–2+1). We saved this molecule with the two directly repeated plasmids “ Hybrid–1+1”. We then joined a copy of both plasmids by selecting the unique EcoRI site in pBR322, selecting Edit | Copy, then selecting the EcoRI site in pBR322+ and choosing Edit | Paste. We used pBR322 and introduced a fifth FspI site by changing the T at 2788 to a C, creating pBR322+. You can simulate this in MacVector by creating concatenated fake plasmids counting the two variant plasmids. You might come across this type of scenario if you have been making site-specific mutations and introducing new restriction sites into a vector where only some of the resulting plasmids might have acquired the extra site. We had a recent support call this week from somebody who believed from their agarose gels that they had a mixed population of plasmids from an experiment and wanted to document and determine the banding pattern using MacVector’s agarose gel simulation.
