DNA (deoxyribonucleic acid) was the nucleic acid that served as the basis for carbon-based life. (TV: School Reunion ^[+]Loading...["School Reunion (TV story)"]) It was noted for its double-helix shape, at least in human societies. (TV: Evolution of the Daleks ^[+]Loading...["Evolution of the Daleks (TV story)"]) In the 20th century the scientists James Watson, Crick, and Wilkins made substantial discoveries regarding DNA for which they won the Nobel Prize in 1962. (PROSE: The Taint ^[+]Loading...["The Taint (novel)"]) A guide for time travellers recommended that one do not edit their own DNA at home.

In an alternate Paris of 1804, Garce and Eging commented on the idea of the double-helix, finding it ridiculous that two snakes coiled together were inside all humans. (PROSE: The Man in the Velvet Mask ^[+]Loading...["The Man in the Velvet Mask (novel)"])

According to the Eighth Doctor, he had quadruple-helix DNA, but only three out of the four strands were visible to non-temporally aligned scanners (therefore part of his DNA was linked to the Time Vortex). (PROSE: Frontier Worlds ^[+]Loading...["Frontier Worlds (novel)"])

By placing her hand on the casing of the "Metaltron", the biomass of the human time traveller Rose Tyler was extrapolated and so regenerated the Dalek. However, this had the side-effect of mutating the Dalek, leading to it to self-destruct. (TV: Dalek ^[+]Loading...["Dalek (TV story)"])

DNA that did not code for a protein was classed as "non-coding". (TV: School Reunion ^[+]Loading...["School Reunion (TV story)"])

DNA bombs attacked their victims by latching on to their DNA. (TV: Kiss Kiss, Bang Bang ^[+]Loading...["Kiss Kiss, Bang Bang (TV story)"], The Woman Who Fell to Earth ^[+]Loading...["The Woman Who Fell to Earth (TV story)"])

The Eleventh Doctor once claimed to Jack, a reader of Doctor Who Adventures, that Time Lord DNA went "knit one, purl one" when explaining the possibility that Time Lords descended from knitwear.

A sentient cell culture known as the Culture was endangered by an infection of viruses which inserted their DNA into the Culture cells, turning them into nurseries for incubation of more invaders. (COMIC: Culture Shock! ^[+]Loading...["Culture Shock! (comic story)"])

The Department implanted human DNA in CCPCs during experiments. (TV: Mutant Copper ^[+]Loading...["Mutant Copper (TV story)"]) As claimed by Inspector Thorne, Trojan was created from the DNA of every species encountered by the Department, including Jixen, Anubian and Meron. Regarding Trojan's breath, K9 Mark 2 facetiously suggested to Thorne that he may incorporate some "breath mint DNA" next time. (TV: The Eclipse of the Korven ^[+]Loading...["The Eclipse of the Korven (TV story)"])

All Skarosian life had DNA, (AUDIO: Corruption ^[+]Loading...["Corruption (audio story)"]) which was fundamental type 467-989. (TV: Daleks in Manhattan ^[+]Loading...["Daleks in Manhattan (TV story)"]) According to the War Doctor, the Thals and Kaleds had the same DNA, though Kaled DNA was sufficiently different from that of a Dalek mutant that a Dalek could not operate technology coded to respond only to a Thal or Kaled.

In late 2023, foundling Ruby Sunday signed up for a television show hosted by Davina McCall which would submit her DNA to various databases to find biological relatives. However, despite McCall's show having access to a wide number of databanks, Ruby's DNA had no matches. (TV: The Church on Ruby Road ^[+]Loading...["The Church on Ruby Road (TV story)"])
