Open Reading Frame Finder for DNA Sequences

Our free ORF finder tool detects open reading frames in DNA sequences, identifying potential protein-coding regions. ORF detection is a fundamental step in gene finding and genome analysis, helping researchers identify coding sequences within genomic data. The tool searches for start codons (ATG) and stop codons (TAA, TAG, TGA) across all three reading frames to locate the longest open reading frame.

The ORF finder analyzes your DNA sequence in all three reading frames, identifying the longest open reading frame with precise start and stop positions. This information is crucial for sequence analysis, genome assembly, and understanding gene structure. Use our main sequence analyzer for comprehensive analysis, DNA translation tool to convert ORFs to protein sequences, or our GC content calculator for sequence composition analysis.

All ORF detection is performed instantly in your browser with complete privacy. The ORF finder is essential for bioinformatics researchers, molecular biologists, and students working on genome analysis projects, providing accurate identification of potential protein-coding regions in DNA sequences.
