DNA replication
Let an agent explain DNA replication and its mechanism and machinery, describe differences between prokaryotic and eukaryotic replication and variants, support learning and research questions, and describe its relevance to medicine and biotechnology.
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 replication and its mechanism and machinery, describe differences between prokaryotic and eukaryotic replication and variants, support learning and research questions, and describe its relevance to medicine and biotechnology.
The biological process by which a cell copies its DNA before division, producing two identical double helices by unwinding the parent molecule and synthesising complementary strands with enzymes such as helicase, primase, DNA polymerase and ligase, semi-conservatively and in both prokaryotes and eukaryotes with differences in origins, machinery and regulation, and in variants such as endoreduplication where the genome is copied without cell division; DNA replication is fundamental to heredity and is studied in molecular biology.
What it is for: Copying DNA before cell division.
It can be explain the mechanism; describe prokaryotic and eukaryotic differences; support learning; describe applications.
Distinguishing features
Semi-conservative
Origins of replication
Leading and lagging strands
High fidelity
What it looks like
Not physical; a molecular process shown in diagrams.
How it is recognised
Semi-conservative copying of DNA
Helicase, primase, polymerase, ligase
Transcription copies DNA to RNA; PCR is artificial amplification
