How were the organelle reference sequences chosen?

We found most of the reference sequences by their GenBank titles (e.g., Homo sapiens mitochondrion, complete genome). The accession numbers of additional sequences were found on other organelle websites. We selected only one organelle reference sequence per organism. If more than one complete organelle genome has been sequenced from an organism, we selected as the reference the sequence most often cited in the literature, or the one with the most complete set of features annotatead.

The date on these reference sequences is more recent than that on the original record. Why?

The date displayed is the date on which the Reference Sequence record was created. The reference sequences were made from the original GenBank files. These original records are still in GenBank.

How did you choose the common names for the organisms?

If the NCBI's taxonomy database contains a preferred common name for an organism, that name is displayed. For other organisms, we display either one of the common names (for example, 'donkey' for Equus asinus), the common name of a parent taxonomic node (for example, 'door snail' for Albinaria coerulea), or a common name chosen by a member of the NCBI's taxonomic staff (for example, 'peregrine falcon' for Falco peregrinus).

Are there any tools on this site that will help me curate the mitochondrial genome I am sequencing?

Yes. We have created a mitochondria protein sequence database. You can use BLAST to compare your sequence to other mitochondrial proteins, selected by taxonomic grouping.
