ORF finder

Find open reading frames in all six reading frames of a DNA sequence. For each ORF you get its strand, frame, coordinates, length and the translated protein — the first step in characterising any new gene.

0 bases · Spaces, line numbers and FASTA headers are removed automatically.

Open reading frames, longest first

Good to know

Longest is not always the real one

The longest ORF is a good first candidate, but real genes are confirmed by homology (BLAST), start-site context and expression evidence. Treat this list as candidates, not conclusions.
