any of a group of organic substances found in the chromosomes of living cells and viruses that play a central role in the storage and replication of hereditary information and in the expression of this information through protein synthesis.

DNA

(biochemistry)

DNA

deoxyribonucleic acid; a nucleic acid that is the main constituent of the chromosomes of all organisms (except some viruses). The DNA molecule consists of two polynucleotide chains in the form of a double helix, containing phosphate and the sugar deoxyribose and linked by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA is self-replicating, plays a central role in protein synthesis, and is responsible for the transmission of hereditary characteristics from parents to offspring

Cross linked plasmid DNA-gelatin nanospheres containing about 25-30% DNA were found to be more resistant to nuclease digestion than naked DNA and induced greater gene expression in mice after intramuscular injection (17).
On the other hand, DNA has been also employed as a free molecule (naked DNA).
We are using the so-called naked DNA. As far as we know, naked DNA poses none of the risks associated with viral vectors.

Heterologous prime/boost vaccination strategies employing recombinant bacteria, viruses, proteins, and naked DNA have been shown to elicit stronger and more diverse cellular immune responses than BCG vaccine alone [5-7, 22].
Indeed, injection of free DNA (naked DNA) stimulates effective and long time immune responses to the protein (antigen) encoded by the gene vaccine, which is being considered "the third generation vaccines".
Vaccines currently under development include subunit vaccines (9), naked DNA vaccines (10,11), and attenuated mycobacteria, including recombinant BCGs expressing immunodominant antigens and cytokines (12).
For 2 decades, away from the noise of the latest ups and downs for viral vectors, chemists and materials scientists have been doggedly investigating and improving on other strategies such as using capsules that protect and guide DNA into cells and methods of introducing naked DNA. Though these techniques remain works in progress, they may eventually present a safer alternative to viral transporters of DNA.
The naked DNA or the adenoviruses are simply a means of getting any kind of gene expressed.

The gene can be introduced into a mammalian host by way of an expression vector either as naked DNA or complexed to lipid carriers, particularly cationic lipid carriers.
