General Directions for ASN1 Format

Some GenBank tools use the ASN1 format. (GenBank also supports FASTA format which is more commonly used.) Also submissions of mtDNA FGS data to GenBank are in ASN1 format.

Please make note of the following:

Brief directions:

  1. Go to GenBank.
  2. Find an mtDNA sequence you want. (Search "Nucleotide" for the sequence ID, or "homo sapiens mitochodrion" or use my sequence.)
  3. In the upper right corner click on "Send".
  4. In the popup menu select "Complete Sequence" and "File", choose format "ASN.1" and press the "Create File" button.
  5. Save the downloaded ASN1 file somewhere on your computer.
  6. Click on the "Browse" button on the mthap page and select the ASN1 file.
  7. Click on "Upload."
