Learning goals
Connect amino acid codes, DNA codons, codon degeneracy, and deterministic models
- Have students open the generator and enter a first name.
- Ask them to record the amino acid sequence and DNA codons.
- Use Shuffle to show that codons can change while amino acids stay the same.
- Send students to the codon table to decode or compare sequences.

Why use DNA My Name in class?
Abstract concepts like codons, amino acids, and the genetic code become concrete when students can encode something personal — their own name. DNA My Name gives each student a unique, deterministic DNA sequence derived from their name, creating immediate engagement and a natural springboard for deeper biological discussion.
- No account or login required — students can use it instantly. Names aren't stored; we use anonymous analytics to improve the tool.
- Works on any device with a browser
- Results are shareable as links or downloadable as images
- Free, with no ads or in-app purchases
Curriculum connections
DNA My Name supports learning objectives in:
- The central dogma — DNA encodes RNA, which encodes proteins. This tool focuses on the DNA → protein mapping step using the real genetic code.
- Codons and the genetic code — students can observe that amino acids are encoded by triplets of nucleotides (A, T, G, C), and that many amino acids have multiple synonymous codons (codon degeneracy).
- Amino acid alphabet — the tool reveals that biology uses a 20-letter amino acid alphabet that does not map one-to-one to the 26-letter English alphabet, provoking discussion about why.
- Determinism in biology — the same sequence of codons always produces the same amino acid sequence, illustrating how genetic information is stored and read.
- Bioinformatics introduction — the concept of a seed-based PRNG for reproducible results bridges biology and computer science.
* Aligns with NGSS (US), STEELS (PA), AQA/OCR (UK), and equivalent secondary biology curricula.
Name → Amino Acid mapping
Every letter in a name maps to an amino acid using the one-letter amino acid code. Six letters (B, J, O, U, X, Z) are not standard amino acid codes and are substituted with biochemically related amino acids.
| Letter | Amino Acid |
|---|---|
| A | Alanine (A) |
| B* | Aspartic Acid (D) |
| C | Cysteine (C) |
| D | Aspartic Acid (D) |
| E | Glutamic Acid (E) |
| F | Phenylalanine (F) |
| G | Glycine (G) |
| H | Histidine (H) |
| I | Isoleucine (I) |
| J* | Leucine (L) |
| K | Lysine (K) |
| L | Leucine (L) |
| M | Methionine (M) |
| N | Asparagine (N) |
| O* | Lysine (K) |
| P | Proline (P) |
| Q | Glutamine (Q) |
| R | Arginine (R) |
| S | Serine (S) |
| T | Threonine (T) |
| U* | Cysteine (C) |
| V | Valine (V) |
| W | Tryptophan (W) |
| X* | Glycine (G) |
| Y | Tyrosine (Y) |
| Z* | Glutamic Acid (E) |
* Substituted letter — no standard amino acid exists for this letter code.
Classroom activity ideas
Activity 1: Decode a classmate’s sequence
Generate a DNA sequence for a name and challenge students to reverse-engineer the amino acid sequence using the codon table. Then map it back to letters. Discuss: why are some translations ambiguous?
Activity 2: Codon degeneracy exploration
Use “Shuffle” to generate multiple DNA variants for the same name. Ask students: do the amino acid sequences change? Why or why not? The Silent mutation check highlights changed codon pairs so students can see synonymous mutations and the concept of wobble base pairs.
Activity 3: Substitution mapping
The letters B, J, O, U, X, Z require substitution. Ask students: why don’t these letters map directly to amino acids? Research the biochemical relationship between the substituted pairs (e.g., U→C: both have sulfur-containing side chains).
Activity 4: G.E.N.E Index comparison
Use the Compare DNA feature to calculate similarity scores between names. Discuss: what does DNA similarity actually mean in real biology? How does genetic distance relate to evolution and species classification?
Discussion prompts
- If the same name always gives the same DNA, what does that tell you about how genetic information is stored?
- Real human DNA has about 3 billion base pairs. How many base pairs does a typical name generate with this tool? What does that ratio suggest?
- Why might it be useful that multiple codons can encode the same amino acid? (Hint: think about mutations.)
- The tool assigns Methionine (M) only to the letter M, with a single codon (ATG). Why is ATG special in real biology?
- What are the limitations of using a name-to-DNA tool as a model of real genetics?

Important disclaimer for educators
DNA My Name uses real codon biology but generates entirely fictional sequences. It is not a genetic testing or ancestry tool. The sequences produced are not meaningful outside this application. Please communicate to students that this is a creative educational model, not a representation of their actual genetic makeup.
