naked DNA


Also found in: Dictionary, Thesaurus, Legal, Encyclopedia, Wikipedia.
A purified DNA sequence with no associated proteins. An immune response can be evoked by directly injecting into the host DNA that encodes an immunogen of interest

naked DNA

DNA that has been modified to remove the proteins that normally surround it. It is used for genetic transfers and vaccine manufacture.
