About the DNA to mRNA Converter
Transcribes a DNA sequence into mRNA, with base-by-base display, validation, and sequence stats.
What it is
Paste a DNA sequence, choose whether it represents the coding (sense) or template (antisense) strand, and the tool transcribes it into the mRNA transcript instantly, following the correct rule for each strand type.
Features
Coding/template modes
Coding strand is copied with T→U; template strand is complemented and read 5'→3'.
Reverse mRNA→DNA
Toggle reverse mode to derive the coding DNA strand from an mRNA sequence.
Base-by-base aligned display
Color-coded monospace output makes the substitution visually obvious.
Validation
Non-ACGT characters are flagged at their exact position, not silently dropped.
GC content & base stats
Sequence length, base counts, and GC/AT percentage shown automatically.
Copy button
Copy the resulting mRNA (or DNA) sequence with one click.
