DNA Sequence Tools (Complement, Transcription, Translation)
Reverse complement, complement, RNA transcription, protein translation, GC content, length and molecular weight of a DNA sequence.
How to use the DNA Sequence Tools
- Enter or select: DNA sequence (plain or FASTA).
- The results (Length, GC content, Molecular weight (dsDNA), Molecular weight (ssDNA), Reverse complement, Complement, mRNA (transcribed), Protein (frame 1), Base counts) are calculated instantly as you type.
- Use “Copy link” to share the calculation with the same input values.
Formula
- GC% = (G + C)/N × 100
- MW(ssDNA) = Σ nᵢ·Mᵢ − 61.96
About this tool
Translation uses the standard genetic code; * marks stop codons. IUPAC ambiguity codes are accepted for complements.
