Linker DNA is double stranded DNA in between two nucleosome cores that, in association with histone H1 , holds the cores together. Linker DNA is seen as the string in the beads and string model, which is made by using an ionic solution on the chromatin. Linker DNA connects to histone H1 and histone H1 sits on the nucleosome core. Linker DNA is not associated with the transcribable DNA wrapped around the core. Nucleosome is technically the consolidation of a nucleosome core and one adjacent linker DNA however, the term nucleosome is used freely for solely the core.

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. Research on the use of naked DNA for DNA vaccination s and gene therapy has shown some initial success, but have not yet resulted in any generally available therapy.
