gene expression
Let an agent explain gene expression and its regulation, describe measurement methods, relate expression to development and disease at a general level, and support biology learning.
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 gene expression and its regulation, describe measurement methods, relate expression to development and disease at a general level, and support biology learning.
The process by which information in a gene is used to produce a functional product such as a protein or RNA, through transcription, RNA processing and translation, regulated so that genes are expressed in specific cell types, stages and conditions, with phenomena such as genomic imprinting, sex-specific expression and induced expression of genes such as ACE2; gene expression is measured by RNA and protein assays and is central to biology and medicine.
What it is for: Turning genes into products.
It can be explain expression and regulation; describe measurement methods; relate to development and disease; support learning.
