Enter your DNA Sequence, choose your DNA Strand Type (coding or template) and Genetic Code, and the DNA to mRNA Converter will transcribe your sequence into the corresponding mRNA Sequence — plus translate it into a Protein Sequence with the full Amino Acid breakdown and Sequence Length.

DNA uses thymine (T) while mRNA uses uracil (U). DNA is double-stranded and contains deoxyribose sugar, while mRNA is single-stranded and contains ribose sugar. mRNA is synthesized from DNA during transcription.
To transcribe DNA to mRNA, replace each DNA base with its complement: A→U, T→A, G→C, C→G. If using the template strand, create the complement. If using the coding strand, simply replace T with U.
The template strand is complementary to the mRNA sequence and serves as the template during transcription. The coding strand has the same sequence as mRNA (except T instead of U) and is also called the sense strand.
mRNA is translated to protein using the genetic code, where every three nucleotides (codon) specify one amino acid. Translation begins at a start codon (AUG) and ends at stop codons (UAA, UAG, UGA).
The three main types of RNA are: mRNA (messenger RNA) that carries genetic information, tRNA (transfer RNA) that brings amino acids during translation, and rRNA (ribosomal RNA) that forms the structure of ribosomes.
Different genetic codes exist because some organisms (like mitochondria) use slightly different codon assignments than the standard genetic code. This affects which amino acids are produced during translation.
