* The Humanoid Cylons in ''Series/BattlestarGalactica'' are a race of [[ArtificialHuman synthetic beings]]. Their DNA is completely artificial. {{Subverted}} in that they're still genetically compatible with humans and a genetic test would indicate they are indeed human, though they still identify as machines.

* ''Manga/ElfenLied'': Among the many other things the Vector Virus does, such as granting PsychicPowers and causing the development of large horns, it also causes the Diclonius to experience a "DNA Voice". This is basically a natural force they all experience that compels them to KillAllHumans and replace them with their own species. It's left ambiguous whether this voice actually exists or it's actually the result of the constant abuse, neglect, and hatred the Dicloni experience from humans that causes it.

* ''Franchise/{{Alien}}'': The Xenomorphs have what's called a "DNA Reflex," which is apparently why they end up looking similar to their host species. This is further elaborated on in [[AllThereInTheManual novels and guides, such as The Weyland-Yutani Report]]. The Chestburster functions much like a cancer, being built from the body's own cells and integrating 10-15% of its DNA in order to prevent an immune response. This causes the Xenomorph to develop similar physical traits, possibly mental ones as well, such as a specific gait or physical features. The reverse is also true; the host has some of the Xenomorph's genetic material integrated into its body during the Chestburster's incubation. This is why Ripley's clone in ''Film/AlienResurrection'' is a HalfHumanHybrid.

* ''VideoGame/{{Fallout}}'': In a world set after a nuclear war, there are bound to be countless genetic abnormalities out in the wasteland. However, one pre-war example would be the experiments performed in the Pan-Immunity Virion Project. In their goal to protect America's population from Chinese bioweapons, they created a retrovirus that could transform all the DNA in a host cell into a quad-helix structure, which they hoped would prevent diseases from taking hold. Their crowning achievement, however, is the Forced Evolutionary Virus. The FEV is described as a Megavirus with a protein sheath reinforced by ionized hydrogen that protects it from radiation. The virus has pre-programmed introns specified for the species it infects. It works by copying the host cell's DNA and placing the data into exons, which is taken back by the virus and then re-introduced into the host's cells alongside the introns, which induce the radical mutations the FEV is known for. [[note]] This is actually a case of ArtisticLicenseBiology; viruses, by definition, can't edit genetic material or replicate on their own. [[/note]]
