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 repair pathways and their biological and medical significance, support learning and research, and provide general information on repair-related conditions without individual medical advice.

The collection of cellular processes that identify and correct damage to DNA, including base and nucleotide excision repair, mismatch repair, double-strand break repair by homologous recombination and non-homologous end joining, photoreactivation and translesion synthesis; defects in DNA repair underlie cancer predisposition syndromes and ageing, and repair pathways are targets of cancer therapy.

What it is for: Maintaining genome integrity.

It can be explain repair pathways and when they act; relate repair defects to diseases; explain repair as a therapy target; find research resources.
