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.

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.

Consequently, when DNA from a foreign source is linked to host sequences that can drive DNA replication and then introduced into a host organism, the foreign DNA is replicated along with the host DNA. Introduction Recombinant DNA molecules are sometimes called chimeric DNA , because they are usually made of material from two different species, like the mythical Chimera mythology chimera . R DNA technology uses palindromic sequences and leads to the production of sticky and blunt ends . The DNA sequences used in the construction of recombinant DNA molecules can originate from any species .
