Did You Know?
Originally titled Do Not Alter, this episode's title was shortened prior to broadcast. The title is shown onscreen with full stops between the letters, but in all official materials since has been displayed without, reflecting how the word is usually written.
DNA is the first episode to confirm the Series IV-onwards retcon (inspired by the novels) of Lister having actually been in a relationship (and broken up) with Kochanski prior to the accident.
The Northern-accented Spare Head Three was based on a routine Robert Llewellyn used to improvise during breaks in filming.
