Inspired by this post I went down the chatgpt rabbithole and made a ecoli-design-lab react app.

Series Title: "E. coli Design" — DNA as an Engineering Language

Premise: Anyone can learn to program biology. DNA is code. Watch as we write it, transform cells, and literally see it change the behavior of life.

📦 Intro Video: The Blueprint of Life (aka DNA = Code)

Set the vision: “You’ve seen code run on a computer. What if we could run code on a living cell?”
Show E. coli swimming, glowing, changing behavior — all controlled by synthetic DNA.
Core ideas: promoter, RBS, CDS, terminator — these are the "functions" of biological programming.

🧪 Module 1: Make E. coli Glow

"Your first genetic program: lighting up a cell."

Construct a simple transcription unit: constitutive promoter + GFP + terminator.
Use a standard vector (e.g., pSB1C3 or pET series).
Transform E. coli → plate → grow → view under blue light.
Discuss how the DNA sequence becomes mRNA → protein → observable trait.

Learning goals:

Plasmid design
Bacterial transformation
Why a promoter matters
Fluorescence basics

🌈 Module 2: Change GFP Color Using a Base Editor

"A few letters changed in DNA... and the color shifts. Welcome to molecular editing."

Use a base editor (e.g. CRISPR-Cas9 nickase fused to a cytidine or adenine deaminase).
Target specific codons in GFP to create YFP or BFP variants.
Use fluorescence imaging to compare.

Learning goals:

Codon changes and amino acids
Introduction to CRISPR base editing
Mutation as a design tool

🌀 Module 3: Make E. coli Spin

"Let's reprogram motility."

Express cheY mutant that biases flagellar rotation.
Could include chemotaxis circuit tweaks.
Cells "tumble" in place instead of swimming forward.

Learning goals:

Bacterial locomotion
Signaling pathways
Flagellar motor basics

💨 Module 4: Speed, Size, and Shape

"What if cells moved faster? Or just... got big?"

Overexpress motA/motB to boost motility.
Express ftsZ mutants or inhibit division (e.g., SulA) to make long filaments.
Add plasmids that affect cell wall biosynthesis to tweak shape (e.g., induce bulges).

Learning goals:

Cell morphology
Cell division machinery
Engineering metabolic load

🧬 Module 5: Uneven DNA Partitioning

"Can we break symmetry in cell division?"

Play with Par system or delete minCDE to disrupt mid-cell division.
Watch daughter cells with uneven contents — some die, some thrive.

Learning goals:

Chromosome segregation
Developmental biology in microbes
Fitness trade-offs

⏱️ Final Module: The Repressilator – Blinking Life

"A genetic oscillator made from DNA logic."

Construct the classic repressilator (LacI-TetR-cI feedback loop).
Observe time-lapse microscopy of fluorescence oscillations.
Sync multiple cells via quorum sensing?

Learning goals:

Synthetic gene circuits
Feedback and control theory in biology
Temporal behavior from static DNA

Host challenges: "Design a toggle switch", "Create an E. coli pattern", etc.
Feature guest modules by researchers and community labs

Would you like help developing a script, lesson plan, or materials for one of these modules? Or even mock up visuals or diagrams for the videos?

are there any simulators that can do this?

Yes — there are several simulators and digital tools that can help you design, simulate, and predict gene expression and synthetic circuits in E. coli. Some even let you visualize expected behaviors like fluorescence intensity, circuit oscillations, or protein levels over time.

Here’s a breakdown of the most useful ones for the kind of E. coli Design series you're thinking of:

🧪 1. iBioSim

Best for: Genetic circuits, oscillators (like the repressilator), logic gates

A visual synthetic biology design tool that simulates genetic networks using ODEs or stochastic models.
You can drag-and-drop parts (promoters, genes, repressors), and simulate time-course data (e.g., how GFP oscillates).
Supports SBOL (Synthetic Biology Open Language), which is an open standard for sharing biological designs.

🌐 https://github.com/MyersResearchGroup/iBioSim
💻 Java-based, open-source

🧬 2. CellDesigner

Best for: Modeling biochemical networks & genetic regulation

Not E. coli–specific, but you can build models of metabolic and gene regulatory networks, with kinetic simulation.
Great for visualizing pathways, feedback loops, and seeing how changing parameters affects outcomes.

🌐 http://www.celldesigner.org/
💻 Free, desktop app (Windows/macOS/Linux)

🧫 3. Tinkercell (discontinued but usable)

Best for: Drag-and-drop circuit design for synthetic biology

Was designed as a visual platform for synthetic biology education.
Lets you model transcriptional units, simulate gene expression, and play with circuit logic.
Though it's no longer actively developed, it still works on many systems.

🌐 https://www.tinkercell.com/
💻 Windows/Linux (may require compatibility settings)

📈 4. COPASI (COmplex PAthway SImulator)

Best for: Detailed biochemical + gene regulation simulations

Can simulate gene expression dynamics, enzyme kinetics, and reactions.
Has stochastic and deterministic solvers.
Not made for synthetic biology per se, but with effort, you can simulate things like repressilators or toggle switches.

🌐 https://copasi.org/
💻 Cross-platform

🧬 5. BioCRNpyler + bioscrape (for Python users)

Best for: Programmable, modular synthetic biology simulation

BioCRNpyler: Build CRNs (Chemical Reaction Networks) from genetic part libraries.
bioscrape: Fast simulation of gene circuits, with deterministic + stochastic options.
Great for coders who want to automate or simulate many designs programmatically.

🌐 https://github.com/BuildACell/bioscrape
🌐 https://github.com/BuildACell/BioCRNpyler
💻 Python-based

👨‍🏫 6. Cello 2.0 (Logic Circuits to DNA)

Best for: Designing logic circuits that get compiled into real DNA sequences

You input a logic truth table (e.g. “IF A AND NOT B, THEN express GFP”) and Cello turns it into a genetic circuit using pre-characterized parts.
Simulates performance in silico and outputs GenBank-ready plasmid maps.

🌐 https://cellocad.org/
💻 Web-based, cloud simulation

🎮 7. Biota or Gene Game–style Apps (limited)

There are experimental or educational games (like Foldit or Eterna for RNA), but fewer aimed at bacterial gene circuit engineering. However, some tools/games are being prototyped (like “Living Computers” or “Cell Architect”) and might evolve in that direction.

🔄 Combine With:

Benchling or SnapGene for DNA design (no simulation, but integrates well)
SBOL Designer for standardized design diagrams
Google Colab + Python for building your own simulators with packages like Tellurium or PySB

✅ Recommendation for Beginners:

Start with iBioSim or Cello 2.0 if you want to visually build circuits and simulate how they'll behave.
For hands-on or coding-literate users, bioscrape + BioCRNpyler gives you real modeling power.

Would you like a starter template in one of these tools (like the repressilator or GFP construct)? I can mock one up for you or walk you through setting it up.

sure

Great! Let’s start with a simple and visual repressilator model using iBioSim — one of the most accessible tools for beginners who want to simulate real synthetic biology circuits without needing to write code.

🧬 What We'll Build:

The Repressilator — a synthetic gene oscillator made of 3 genes:

LacI represses TetR
TetR represses cI
cI represses LacI

Each gene is transcribed and translated, and the resulting proteins repress the next gene in a loop — leading to oscillations (like blinking GFP).

🧰 Step-by-Step: Building the Repressilator in iBioSim

✅ Step 1: Download iBioSim

Go to: 🌐 https://github.com/MyersResearchGroup/iBioSim
Click on Releases and download the latest .jar file (Java required).
Launch it via: java -jar iBioSim.jar

Let me know if you hit any Java install/setup snags — I can walk you through those.

✅ Step 2: Start a New Project

Click: File → New → Project
Name it: Repressilator
Click "Create"

✅ Step 3: Add Species (Proteins)

Open the project and click Model Editor
Add species:
- LacI (protein)
- TetR (protein)
- cI (protein)

These will each represent repressors that inhibit the next gene in the loop.

✅ Step 4: Add Reactions

We’ll simulate simplified gene expression + repression (no full transcriptional detail for now):

LacI production
- Reaction: null → LacI
- Rate: alpha1 / (1 + (cI/K)^n)
TetR production
- Reaction: null → TetR
- Rate: alpha2 / (1 + (LacI/K)^n)
cI production
- Reaction: null → cI
- Rate: alpha3 / (1 + (TetR/K)^n)
Degradation for each
- LacI → null, rate: delta * LacI
- TetR → null, rate: delta * TetR
- cI → null, rate: delta * cI

You’ll enter these in the Reaction View by clicking “+ Add Reaction” and specifying the kinetic laws.

✅ Step 5: Set Parameters

Add the following global parameters:

Parameter	Value	Description
`alpha1`, `alpha2`, `alpha3`	`50`	Max production rate
`K`	`40`	Repression threshold
`n`	`2`	Hill coefficient (cooperativity)
`delta`	`1.0`	Degradation rate

These values are from the original repressilator paper and should produce oscillations.

✅ Step 6: Simulate

Go to Simulation tab
Time: 0 → 500
Click “Simulate”

🌀 You should see oscillations in the levels of LacI, TetR, and cI over time — out of phase like a clock.

📸 Next Step: Add GFP as Output

To make the circuit visible under a microscope:

Add GFP as a species.
Add a reaction: null → GFP
- Rate: alphaGFP / (1 + (cI/K)^n)
Add degradation: GFP → null, rate: delta * GFP

Now GFP will blink in sync with one of the repressors!

✅ Want the .xml or .sbml project file?

I can generate a working iBioSim project file for the repressilator and send it to you (or show you what the SBML looks like). If you're using Python instead (bioscrape, etc.), I can port it too.

Would you prefer:

A downloadable iBioSim project
A Python bioscrape simulation
Or both?

Let me know what system you’re working on (Windows/macOS/Linux) and whether you prefer GUI-based or code-based modeling.

gui based modeling that is open without requiring login

Perfect — in that case, here are the best GUI-based, open-source, no-login-required tools for simulating genetic circuits like the repressilator visually. I'll also provide direct download links and usage notes to get you started today.

✅ Best Option: iBioSim

🧬 Why it’s great:

Fully GUI-based — drag-and-drop genes, repressors, species
No login or online account required
Supports simulation of genetic circuits using deterministic or stochastic models
Can model oscillators, toggle switches, logic gates, etc.

Would you like that ZIP package? Also let me know what OS you're using (Windows/macOS/Linux), and I’ll tailor the files to that environment.

like phet simulations is there not a website where this whole or part of this thing could be implemented?

Ah — now I understand exactly what you're asking. You're looking for something like PhET simulations — fully browser-based, visual, no-login, interactive simulations — but for synthetic biology or genetic circuit design, ideally with the ability to tweak DNA components and see how E. coli behavior changes.

TL;DR:

✅ Some tools kind of do this
❌ But nothing yet fully matches the PhET-level polish and simplicity for genetic circuit simulation in cells like E. coli — especially at the intersection of DNA editing → observable behavior (like swimming, glowing, or dividing).

That said, there are some close contenders — and I’ll outline those below, then explain how this could be built (which is very possible).

🧠 Closest Web-Based Simulators (Visual, No Login)

🧬 1. Cello 2.0

Browser-based, free, no login
Build logic circuits using standard genetic parts (promoters, repressors, etc.)
Inputs: Truth tables → Outputs: DNA sequences and predicted behavior
Great for logic design (e.g., “IF A and NOT B, turn on GFP”)

🟢 Pros:

Realistic synthetic biology model
Visual circuit design

🔴 Cons:

Doesn’t simulate swimming, size, or physical traits
Focused on logic circuits, not behavior dynamics

🔬 2. GenoCAD

Visual DNA sequence design using rules and part libraries
Lets you design transcription units
Web-based and intuitive

🟢 Pros:

Visual DNA design tool
Pre-built promoters, CDS, etc.

🔴 Cons:

No dynamic simulation (e.g., no blinking GFP, motility modeling)

📊 3. Virtual Biology Lab – Genetic Circuits

Some very basic simulators showing gene regulation principles
Sliders for repression, induction, etc.
More educational, less custom

🟢 Pros:

Purely browser-based, easy to use

🔴 Cons:

Oversimplified
Not usable for actual synthetic circuit design

⚙️ 4. Biosimulators.org

Directory of simulation tools that can run in the browser
Uses SBML, COMBINE archives, and BioSimulations platform
Advanced but fragmented — needs SBML input

🟢 Pros:

Open, standards-based
Can simulate many biological models

🔴 Cons:

Not PhET-like
Requires technical setup or model uploads

🧠 Why Doesn’t a PhET-Style E. coli Design Lab Exist Yet?

It really comes down to this:

Simulating DNA → protein → behavioral phenotype is computationally complex
Most tools focus on gene expression, metabolic modeling, or circuit logic
Physical traits (like swimming, size, blinking) require agent-based modeling or biomechanics

🔮 What Would a PhET-Style E. coli Design Simulator Look Like?

Core Features:

Drag-and-drop: Promoters, CDSs, repressors
Preview of plasmid/DNA map
Live output graph: GFP levels, cell growth, oscillations
Toggle between:
- Fluorescence view (e.g., blinking GFP)
- Behavior view (e.g., cells spinning or growing)
No login, runs in browser

Powered by:

SBOL/GenBank parser
Bioscrape/iBioSim backend
Agent-based modeling for physical behavior
WebGL or HTML5 canvas for live simulation

✅ Good News

Something like this absolutely could be built, and there’s growing momentum:

Community labs & DIY bio are hungry for tools like this
SBOL and BioCRNpyler provide the foundation
Visualizations could be built using p5.js or three.js

If you're interested, I could:

Mock up a concept UI for this type of simulator
Create a roadmap or open-source template for building it
Help you launch a prototype if you're developing this as a project

🧩 Summary Table

Tool	Browser	No Login	Circuit Design	Phenotype Simulation
Cello 2.0	✅	✅	✅ Logic gates	❌ No physical traits
GenoCAD	✅	✅	✅ Transcription units	❌
Virtual Bio Lab	✅	✅	⚠️ Very simple	❌
iBioSim (Java)	❌	✅	✅ Advanced	✅ (Gene-level only)
TinkerCell	❌	✅	✅ Legacy	✅ (limited)
Custom simulator	🚧	✅	✅	✅ (Possible!)
