Follow an interactive account of hemoglobin’s structure and see how it binds oxygen, changes shape, and releases oxygen in the body.
Add or remove an input signal and follow protein concentrations in a simplified regulatory circuit.
Compare mutations and generations in an abstract NAND-gate circuit model, using a truth table and fitness score.
Generate directed or undirected random networks by choosing node and edge counts and whether self-loops are allowed.
Step through activator and repressor response curves to connect protein concentration with gene expression.
Explore logic approximations and step through graphs of protein accumulation and depletion over time.
Compare biological transcription networks with random networks and generate graphs to investigate self-regulation.
Step through a controlled model comparison of negative autoregulation and simple gene regulation.

The systems biology series builds from transcription factors to gene-circuit dynamics and autoregulation. Separate playgrounds explore random networks, feed-forward loops and a deliberately abstract evolutionary circuit model.
This selection connects 8 projects across writing, interactive. Follow the project links for the original experience; use the build log for dated context where evidence is available.
