Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

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.

Deoxyribonucleic acid, the biopolymer that carries the genetic instructions of living organisms and many viruses, composed of two strands of nucleotides wound into a double helix and encoding information in the sequence of the bases adenine, thymine, guanine and cytosine; DNA is replicated, transcribed and repaired in cells and is studied and used in genetics, medicine, forensics and biotechnology.

What it is for: Storing and transmitting genetic information.

It can be explain DNA structure, replication and expression; explain DNA testing and its limits; describe forensic and ancestry uses; address ethics and privacy.

Distinguishing features

Double helix

Genetic information carrier

Replicated and repaired

Widely analysed

What it looks like

Not visible to the eye; a double helix at the molecular scale, extractable as white strands.

How it is recognised

Double-stranded nucleic acid with thymine

Carries genes

RNA is single-stranded and contains uracil
