  • Translation started at the beginning of reading frame 1.
  • A stop codon (*) appears after 7 amino acids.
  • An X marks a codon containing an ambiguous base (N).

Translation uses the standard genetic code (NCBI table 1). Mitochondrial and some microbial genomes use variant codes where a few codons differ. The tool performs a plain codon-by-codon translation — it does not model introns, splicing, alternative start codons or post-translational processing.

What is the DNA to RNA Converter?

Transcription copies a DNA sequence into mRNA by replacing every thymine (T) with uracil (U). The mRNA matches the coding strand, so ATGGCC becomes AUGGCC.

  • DNA to mRNA transcription from either strand
  • Complement and reverse complement in 5' → 3' order
  • Protein translation with the standard 64-codon table
  • Three reading frames plus start-at-AUG mode
  • GC content, length and base composition stats
  • 100% local — sequences are never uploaded

How to use the DNA to RNA Converter

  1. 1

    Paste or type your DNA sequence into the box.

  2. 2

    Say whether it is the coding strand or the template strand.

  3. 3

    Pick a reading frame, or choose to start at the first AUG.

  4. 4

    Read the mRNA, complement, reverse complement and protein.

  5. 5

    Copy or download any of the results.

About the DNA to RNA Converter

The ByteTools DNA to RNA Converter transcribes a DNA sequence into messenger RNA and then translates it into protein. Paste a sequence — FASTA headers, line breaks, numbers and spaces are all ignored — and the tool returns the mRNA, the base-for-base complement, the reverse complement and the amino acid chain in both one-letter and three-letter notation.

You can say whether the sequence you pasted is the coding strand or the template strand, because that changes the answer: mRNA copies the coding strand directly, while a template strand has to be reverse-complemented first. Reading frame can be set to 1, 2 or 3, or you can ask the tool to start translating at the first AUG. GC content, sequence length and a full base composition are reported alongside.

Translation uses the standard genetic code with a built-in 64-codon table, and everything runs locally in your browser. No sequence is uploaded or stored anywhere, which matters when you are working with unpublished data.

Frequently asked questions

How do you convert DNA to RNA?

Replace every thymine with uracil. The mRNA transcript matches the coding strand of the DNA, so ATGGCCATT becomes AUGGCCAUU. If you start from the template strand you must take the reverse complement first.

What is the difference between the coding and template strand?

The template (antisense) strand is the one RNA polymerase actually reads, running 3' to 5'. The coding (sense) strand has the same sequence as the mRNA apart from T instead of U, which is why it is the one usually quoted in databases.

What is a reverse complement?

It is the complementary sequence written 5' to 3', so you swap each base for its partner and then reverse the whole string. ATGC becomes GCAT. It is what you need when designing a reverse primer or reading the opposite strand.

How is GC content calculated?

Add the number of guanine and cytosine bases and divide by the total number of unambiguous bases, then multiply by 100. GC-rich sequences have higher melting temperatures because G–C pairs share three hydrogen bonds instead of two.

Which genetic code does the translation use?

The standard code, NCBI translation table 1, where AUG codes for methionine and UAA, UAG and UGA are stop codons. Mitochondrial and some microbial genomes use variant codes in which a few codons differ, so results for those need adjusting.
