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 handle nucleotides by structure, base, role and nomenclature in biochemistry and molecular biology.

An organic molecule made of a nitrogenous base, a five-carbon sugar and one or more phosphate groups; nucleotides are the building blocks of DNA and RNA and also act as energy carriers (ATP) and signalling molecules (cAMP).

What it is for: Genetic information, energy transfer and signalling.

It can be identify nucleotides by base and sugar; explain roles in DNA, RNA and metabolism; use standard nucleotide codes; find chemical data.

Distinguishing features

Base plus sugar plus phosphate

Monomers of nucleic acids

Energy carriers such as ATP

Standard letter codes

What it looks like

Invisible molecules; drawn as structural formulas or letters in sequences.

How it is recognised

Base letters A, C, G, T, U

Ribose or deoxyribose

Nucleosides lack the phosphate
