A UFO is normally considered to be an inanimate object when people are thinking of aliens. It is simply an unidentified flying object and so it could be a life-form such as a bird for example which was unrecognised as being a bird at the time.
If however you are referring to a UFO which is of alien origin then it is unlikely this would possess any DNA as it would likely be a spaceship made up of inorganic material. If you are actually referring to aliens themselves then the answer is unknown as one has never been met.
