DNA My Name
Turn your name into a DNA sequence.

This free name to DNA generator maps each letter to an amino-acid code, then chooses a matching codon from the standard genetic code. See how the conversion works or explore all 64 DNA codons.
This is a playful reverse-mapping demonstration — not real genomics!
The 4 DNA Bases
These four chemical molecules pair together (A with T, G with C) to form the “rungs” of the DNA ladder.
The Central Dogma of Biology: In real cells, DNA encodes proteins through a fascinating process. Each three-letter DNA sequence (codon) codes for one amino acid, and chains of amino acids form proteins. Each amino acid is encoded by exactly 3 base pairs (one codon), so total base pairs = amino acids × 3.
We reverse this process! Each letter of your name maps to an amino acid (A → Alanine, M → Methionine, etc.), then we find a DNA codon that codes for that amino acid.
Why are codons exactly 3 letters? With 4 possible bases at each position, a 3-letter codon gives 4 × 4 × 4 = 64 combinations — just enough to cover 20 amino acids with room for redundancy. A 2-letter code would only give 16!
The "Shuffle" button picks different codons that encode the same amino acids — just like nature's redundancy in the genetic code!
