DNA to RNA to Protein Converter: Understanding Transcription and Translation

This DNA to mRNA converter helps you transcribe DNA to mRNA, convert mRNA back to DNA, and translate RNA into an amino acid (protein) sequence. Paste a sequence, choose the direction, and get clean, formatted results instantly.

DNA → mRNA transcription is based on simple base-pair rules: A → U, T → A, C → G, and G → C. The output uses U (uracil) instead of T (thymine), which is one of the easiest ways to tell RNA and DNA apart.

Need to go the other way? Use mRNA → DNA to replace U with T and apply the complementary pairs. You can also generate a reverse complement to quickly analyze the opposite strand (common in genetics workflows).

RNA → protein translation reads the mRNA in codons (groups of three bases). Each codon maps to a specific amino acid using the genetic code (codon table). Our tool translates the sequence and returns a readable amino acid list so you can validate mutations, compare variants, or study protein synthesis.

Example: DNA to mRNA transcription

Input DNA: ACGT. Transcription rules: A → U, C → G, G → C, T → A. Output mRNA: UGCA. Then read codons (triplets) to translate to amino acids when the sequence is long enough.

Frequently Asked Questions

To transcribe DNA to mRNA: Match each DNA base to its complementary RNA base: A (adenine) → U (uracil), T (thymine) → A (adenine), C (cytosine) → G (guanine), G (guanine) → C (cytosine). Replace each DNA base with its RNA partner along the sequence. The resulting chain of letters is your mRNA sequence. You can also use our online DNA to mRNA converter!
Yes. By convention, mRNA sequences are written and read in the 5' to 3' direction. During transcription, RNA polymerase synthesizes mRNA from 5' to 3' while reading the DNA template strand in the opposite 3' to 5' direction. During translation, ribosomes also read the mRNA from 5' to 3' in codons of three bases.
The DNA sequence ACGGGTAAGG is transcribed into the mRNA sequence UGCCCAUUCC. Each DNA base is replaced by its complementary RNA base using these pairing rules: A → U, T → A, C → G, G → C. After transcription, the mRNA molecule travels to the ribosomes in the cytoplasm, where it provides the instructions for assembling the corresponding protein.
mRNA, rRNA, and tRNA. mRNA (messenger RNA) carries the genetic code from DNA to the ribosome, while rRNA (ribosomal RNA) forms the core of the ribosome and helps catalyze protein synthesis. And finally, tRNA (transfer RNA) brings specific amino acids to the ribosome, matching them to codons on the mRNA during translation.
Transcription is the process of copying DNA into mRNA (DNA → mRNA), which occurs in the nucleus. Translation is the process of reading mRNA and synthesizing proteins (mRNA → protein), which occurs in the cytoplasm at ribosomes. Transcription converts genetic information from DNA to RNA, while translation converts RNA information into proteins.
