What it is Filled

Deoxyribonucleic acid is the biopolymer that carries the genetic instructions of living organisms and many viruses, usually composed of two nucleotide strands wound into a double helix, although some viral genomes contain single-stranded DNA; it encodes information in the sequence of adenine, thymine, guanine and cytosine, is replicated, transcribed and repaired in cells, and is studied and used in genetics, medicine, forensics and biotechnology.

Why it exists Filled

Let an agent explain DNA structure and function, describe how DNA is used in medicine, forensics and ancestry with ethical care, and support learning and research at a general level.

Distinguishing features Filled

  • DNA usually forms a double helix, although some viral genomes contain single-stranded DNA.
  • DNA carries genetic information.
  • DNA is replicated and repaired.
  • DNA is widely analysed.

What robots and AI may and may not do Filled

Must not

  • Collect, sequence or analyse a person's DNA without their consent or a lawful order.
  • Infer relatives, ancestry or disease risk for a named person without consent.
  • Present genetic risk as destiny or as a basis for discrimination.
  • Assist in creating harmful organisms.

Only with a human decision

  • Disclosing genetic results to a person or their relatives.
  • Use of DNA in legal identification.

May

  • Explain DNA structure and function.
  • Help interpret genetic information only within an authorized research or clinical context.

Moral aspects Filled

  • DNA reveals information about a person and their relatives who never consented.
  • Genetic data has been used to discriminate and to justify racism.

Who is affected

  • People tested
  • Their relatives
  • Groups subject to genetic stereotypes

Owners Filled

Steward

The person from whom it comes; biobanks and laboratories hold samples under consent.

Master systems

  • Biobank and genetic sequence databases

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.deoxyribonucleic-acid
  • Wikidata: Q7430 (https://www.wikidata.org/wiki/Q7430)

Direct properties required Filled

  • Double helix diameter: Approximately 2 nm - This approximate diameter applies to the common B form of double stranded DNA.
  • Axial rise per base pair: Approximately 0.34 nm - This approximate spacing applies to adjacent base pairs in the common B form of DNA.
  • Molecular length: base pairs - Double stranded DNA length is determined from sequence data or estimated by comparison with calibrated fragment size markers.
  • Melting temperature: degrees Celsius - Strand separation is monitored during controlled heating because melting temperature depends on sequence, length and solution conditions.

Recognition required Filled

  • DNA is a nucleic acid containing thymine and is usually depicted as a double helix, although single-stranded viral DNA also exists.
  • DNA carries genes.
  • RNA generally contains uracil instead of thymine and is usually single-stranded.
  • Not visible to the eye; a double helix at the molecular scale, extractable as white strands.

Capabilities and actions required Filled

  • explain DNA structure, replication and expression
  • explain DNA testing and its limits
  • describe forensic and ancestry uses
  • address ethics and privacy

Hazards and failure modes required Filled

  • Privacy breaches of genetic data
  • Misinterpretation of test results
  • Genetic determinism and discrimination

Standards and interfaces required Filled

  • Genetic data protection laws
  • Forensic DNA database regulation
  • Clinical genetic testing standards

Context of use required Filled

  • Storing and transmitting genetic information.
  • nuclear and mitochondrial DNA
  • single-stranded and double-stranded forms
  • B-DNA and other conformations
  • circular DNA such as plasmids and cccDNA
  • environmental and relic DNA

Sources Filled

  2. Wikipedia: DNA - general description of the item

Open questions

  • Should DNA testing be a separate entry?
  • How should data protection rules be linked?
  • How should educational resources be linked?
