What is the DNA to RNA Converter?
Convert DNA sequences to RNA in your browser. Choose coding-strand mode (T→U only) for sense-strand sequences, or template-strand mode to reverse-complement then replace T with U for true transcription. Supports FASTA input, GC content, and base counts. Private, free, and instant.
How to use the DNA to RNA Converter
- Select coding strand or template strand transcription mode.
- Paste a DNA sequence (A, T, G, C only) or FASTA text.
- Read the RNA output with U replacing thymine.
- Review T→U conversion count and GC content for DNA and RNA.
- Copy the RNA sequence or full summary.
Common use cases
- Getting mRNA sequence from a published coding-strand DNA sequence
- Transcribing a template strand for molecular biology exercises
- Quick T→U conversion while working with gene sequences
Frequently asked questions
- How does DNA to RNA conversion work?
- In RNA, uracil (U) replaces thymine (T). On the coding (sense) strand, the RNA sequence matches the DNA sequence with T→U. Transcription from the template strand uses the reverse complement first, then T→U.
- What is the coding strand?
- The coding (sense) strand runs 5′→3′ with the same base order as the mRNA (except T in DNA becomes U in RNA). It is not the strand read directly by RNA polymerase.
- What is the template strand?
- The template (antisense) strand is complementary to the mRNA. RNA polymerase reads it 3′→5′ to synthesize mRNA 5′→3′.
- Does it support FASTA files?
- Yes. Header lines starting with > are removed automatically.
- Is my sequence stored or uploaded?
- No. Conversion runs entirely in your browser.
