DNA to mRNA Converter
Transcribe and translate genetic sequences. Enter a DNA sequence to find its complementary DNA strand, transcribed mRNA, and translated amino acid sequence.
Sequence Input
Enter DNA bases (A, T, C, G).
Transcription & Translation
Complementary DNA (3' → 5')

Protein (Amino Acids)
Central Dogma of Biology
DNA is transcribed into messenger RNA (mRNA), which is then translated by ribosomes into amino acid polypeptide chains (proteins).
Standard Genetic Codon Translation Reference Table
| First Base (5') | Second Base | Third Base (3') | Amino Acid Name | Abbreviation |
|---|---|---|---|---|
| A | U | G | Methionine (Start Codon) | Met / M |
| U | U | U, C | Phenylalanine | Phe / F |
| G | A | U, C | Aspartic Acid | Asp / D |
| U | A / G | A, G | Stop Codons (UAA, UAG, UGA) | Stop |

Complementary base pairing governs transcription and replication:
The Genetic Code
There are 64 possible 3-letter RNA codons (4³ = 64) encoding 20 standard amino acids and 3 stop signals.
Frequently Asked Questions
What is the difference between Transcription and Translation? ▼
Transcription is the process where RNA polymerase copies a DNA template strand into a complementary messenger RNA (mRNA) sequence in the cell nucleus. Translation takes place at the ribosome in the cytoplasm, converting the mRNA codon sequence into a functional amino acid chain (protein).
What is the difference between the Coding and Template DNA strands? ▼
The template strand (3' to 5') is actively read by RNA polymerase to synthesize mRNA. The coding strand (5' to 3') has the exact same sequence as the mRNA product, except Thymine (T) in DNA is replaced by Uil (U) in RNA.
What are the start and stop codons in genetic translation? ▼
The universal start codon is AUG, which codes for Methionine (Met) and signals the start of translation. The three stop codons are UAA, UAG, and UGA, which terminate polypeptide chain elongation.
