A DNAvirus is a virus that has DNA as its genetic material and replicates using a DNA dependent DNA polymerase . The nucleic acid is usually double stranded DNA dsDNA but may also be single stranded DNA ssDNA . DNA viruses belong to either Group I or Group II of the Baltimore classification system for viruses. Single stranded DNA is usually expanded to double stranded in infected cells. Although Group VII viruses such as hepatitis B contain a DNA genome, they are not considered DNA viruses according to the Baltimore classification, but rather reverse transcribing viruses because they replicate through an RNA intermediate. Group I dsDNA viruses Order Caudovirales Family Myoviridae includes Enterobacteria phage T4 Family Podoviridae Family Siphoviridae includes Enterobacteria phage lambda Enterobacteria phage &lambda Order Herpesvirales Family Alloherpesviridae Family Herpesviridae includes human herpesviruses, chicken pox Varicella Zoster virus Family Malacoherpesviridae Unassigned families Family Ascovirus Ascoviridae Family Adenoviridae includes viruses which cause human adenovirus infection Family Asfarvirus Asfarviridae includes African swine fever virus Family baculovirus Baculoviridae ...

DNA origami is the nanoscale folding of DNA to create arbitrary two and three dimensional shapes at the nanoscale . The specificity of the interactions between Complementarity molecular biology complementary base pairs make DNA a useful construction material through design of its base sequences. Developed by Paul Rothemund at the California Institute of Technology , the process involves the folding of a long single strand of virus viral DNA aided by multiple smaller staple strands. These shorter strands bind the longer in various places, resulting in various shapes including a smiley face and a coarse map of China and Americas the Americas , along with many three dimensional structures such as cubes. To produce a desired shape, images are drawn with a Raster graphics raster fill of a single long DNA molecule . This design is then fed into a computer program which calculates the placement of individual staple strands. Each staple binds to a specific region of the DNA template, and thus due to Watson Crick base pair Watson Crick base pairing the necessary sequences of all staple strands are known and displayed.

Unreferenced date February 2007 Exogenous DNA refers to any DNA deoxyribonucleic acid that originates outside of the organism of concern or study. The introduction of exogenous DNA into a cell is called transfection . This can take place naturally, as occurs when a virus infects cells, or artificially. Methods of artificial transfection include a chemical methods, including calcium phosphate precipitation, DEAE dextran complexation and lipid mediated DNA transfer b physical methods, including electroporation, microinjection, and biolistic particle delivery gene gun and c using recombinant, lab manipulated viruses as vectors. The process by which cells take up exogenous DNA from the outside is called Transformation genetics transformation . Bacteria need to be in a certain physiological state to successfully take up exogenous DNA, which is described as one of competence. Some bacteria are naturally competent, but usually only for a brief time at a certain stage of their growth cycle. Bacteria can also be made competent through a variety of chemical treatments including exposure to calcium ions, or a mixture of polyethylene glycol and dimethylsulfoxide, which make the cell membrane more permeable, leading to the uptake of the exogenous DNA. Another treatment method is the ustilisation of electricity as the membrane permeabilizing agent electroporation or electrotransformation . Finally, liposome mediated transformation can be used. In this method DNA is coated with lipid. Fusion of this lipid and the membrane lipid can occur, facilitating the entry of DNA.
