Naked DNA is histone free DNA that is passed from cell to cell during a gene transfer process called transformation genetics transformation or transfection . In transformation, purified or naked DNA is taken up by the recipient cell which will give the recipient cell a new characteristic or phenotype . Transfection differs from transformation since the DNA is not generally incorporated into the cell s genome, it is only transiently expressed. In the field of DNA vaccines or genetic immunization, the term naked DNA was coined by Vical to mean DNA delivered free from agents which promote transfection.
