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 nucleic acid sequences and their notation, describe functional sequence elements, support sequence analysis and database use, and relate sequences to genetics and medicine at a general level.

The order of nucleotides in a DNA or RNA molecule, represented as a string of the letters A, C, G and T or U, constituting the primary structure that encodes genes, regulatory sequences, packaging signals, polyadenylation signals and other functional elements; nucleic acid sequences are determined by sequencing, stored in databases, compared by alignment and analysed in bioinformatics, genetics and medicine.

What it is for: The order of nucleotides in DNA or RNA.

It can be explain notation and structure; describe functional elements; support analysis and databases; relate to genetics and medicine.

Distinguishing features

How it is recognised

String of A, C, G, T or U

Primary structure
