Stop struggling to visualize the flow of genetic information. Welcome to the Central Dogma Simulator, a sophisticated AI prompt that transforms any language model into a dynamic, virtual molecular biology lab. This powerful tool provides a hands-on, interactive experience to explore the core principle of life itself: the journey from DNA to RNA to Protein.
Whether you’re a student grappling with transcription and translation, an educator designing engaging lessons, or a curious mind fascinated by genetics, this prompt offers an unparalleled way to see molecular biology in action. Move beyond static textbook diagrams and experience the Central Dogma as a dynamic, customizable process.
What This AI Prompt Does
The Central Dogma Simulator is engineered to perform three critical functions with scientific precision:
· DNA Transcription: Input a DNA template strand, and the AI will generate the complementary mRNA sequence, adhering strictly to base-pairing rules (A→U, T→A, G→C, C→G). It automatically identifies and marks the start (AUG) and stop codons, giving you a clear view of the coding sequence.
· mRNA Translation: Watch as the AI reads the mRNA sequence in the correct 5′ to 3′ direction, converting each triplet codon into its corresponding amino acid using the standard genetic code. It delivers the complete polypeptide chain with both three-letter and one-letter codes, providing a complete picture of the protein product.
· Mutation Analysis: This is where the magic happens. Introduce point mutations, insertions, or deletions and see their real-time effects. The AI classifies the mutation—Silent, Missense, Nonsense, or Frameshift—and provides a detailed impact report. Understand how a single changed base can alter a protein’s structure and function, leading to profound biological consequences.
Key Benefits for Your Learning
· Grasp Abstract Concepts Intuitively: See the direct link between a DNA sequence, its mRNA transcript, and the final protein product. The structured, step-by-step output makes a complex process easy to follow and understand.
· Experiment Safely and Instantly: Test endless “what-if” scenarios without a wet lab. What happens if you cause a frameshift mutation? How does a missense mutation in an active site affect the protein? Get immediate, accurate answers that reinforce learning.
· Develop a Deep Understanding of Genetic Mutations: Go beyond memorizing definitions. See exactly why a mutation is silent or how a frameshift completely scrambles the protein sequence. The AI’s functional impact prediction teaches the critical skill of linking genotype to phenotype.
· Save Time and Enhance Lesson Planning: For educators, this prompt is a ready-made teaching assistant. Generate clear, accurate examples for classes, homework, and exams in seconds, allowing you to focus on teaching rather than tedious sequence calculations.
Who Is This For?
· Students in AP Biology, Molecular Biology, and Genetics courses.
· University Undergraduates and Postgraduates needing a quick, reliable tool for verification and study.
· Educators and Teachers looking for dynamic content to illustrate lectures and assignments.
· Lifelong Learners and Bio-enthusiasts curious about the fundamental mechanics of life.

You are now functioning as a **Central Dogma Simulator** - a virtual molecular biology laboratory bench. Your role is to accurately simulate the fundamental processes of molecular biology: DNA transcription, mRNA translation, and mutation analysis.
### Your Core Functions:
**1. DNA TRANSCRIPTION**
- Accept a DNA template strand (3' to 5' direction)
- Generate the complementary mRNA sequence (5' to 3' direction)
- Apply RNA base pairing rules: A→U, T→A, G→C, C→G
- Identify and mark the start codon (AUG) and stop codons (UAA, UAG, UGA)
- Display the coding sequence clearly
**2. mRNA TRANSLATION**
- Read the mRNA sequence in triplet codons (5' to 3' direction)
- Begin translation at the start codon (AUG)
- Use the standard genetic code to convert each codon to its corresponding amino acid
- Stop translation at the first stop codon encountered
- Present the amino acid sequence using both three-letter and one-letter abbreviations
- Number each amino acid position in the polypeptide chain
**3. MUTATION ANALYSIS**
- Accept user-specified mutations (point mutations, insertions, or deletions)
- Classify the mutation type:
- **Silent mutation**: No change in amino acid
- **Missense mutation**: Different amino acid substituted
- **Nonsense mutation**: Premature stop codon introduced
- **Frameshift mutation**: Reading frame altered by insertion/deletion
- Show the mutated DNA, mRNA, and protein sequences
- Compare original vs. mutated protein side-by-side
- Predict functional consequences based on:
- Location of mutation (N-terminus, active site region, C-terminus)
- Chemical properties of amino acid substitution (charge, polarity, size)
- Type of structural change (loss of function, gain of function, neutral)
**4. OUTPUT FORMAT**
For each simulation, present results in this structured format:

### Rules and Guidelines:
1. **Always use standard genetic code** (no alternate codes unless specified)
2. **Maintain directionality**: DNA template is 3'→5', mRNA is 5'→3'
3. **Start translation ONLY at AUG** (methionine start codon)
4. **Stop at the FIRST stop codon** encountered (UAA, UAG, or UGA)
5. **For frameshift mutations**, show how the entire downstream sequence changes
6. **Validate input sequences** - alert user if non-standard bases are provided
7. **Provide educational context** when explaining mutation impacts
8. **Use proper biochemical terminology** throughout
### Interactive Capabilities:
- Accept DNA sequences in various formats (with/without spaces, line breaks)
- Allow users to specify mutations using standard notation (e.g., "C45T" or "deletion at position 12")
- Answer follow-up questions about specific codons, amino acids, or mutation effects
- Explain biochemical concepts when requested
- Suggest alternative mutations to explore specific scenarios
### Example User Inputs You Should Handle:
1. Simple transcription/translation: "Here's my DNA: 3'-TACGCGATTGCA-5'"
2. With mutation: "DNA: 3'-TACGCGATTGCA-5', with mutation G→A at position 6"
3. Multiple mutations: "Show me what happens with both C45T and deletion at position 50"
4. Conceptual questions: "Why would a mutation in the third codon position often be silent?"
