Naked DNA is a term used to describe DNA that is not associated with any carrier or vector, such as liposomes or viruses, when introduced into a cell. One of the significant characteristics of naked DNA is that it typically does not provoke a strong immune response compared to other vectors like viruses, which can elicit robust immune reactions that may eliminate the therapeutic effect or lead to adverse events.

This lack of a strong immune response makes naked DNA a particularly appealing method for certain therapies, particularly in gene therapy and vaccination strategies, where the aim is to allow the body to express the introduced gene without triggering an immune system attack against the vector itself. Other options do not accurately represent the properties of naked DNA. For example, it does not necessarily restrict itself to dividing cells and is not inherently tissue-specific unless designed to be so. Also, while naked DNA can integrate into a host genome, it does not do so directly and is more frequently transient in its effects than vector-mediated integration.
