Table 2. Distribution statistics for binomial name and genus-level taxonomic affiliation of CRISPRdb direct repeats.
A library of direct repeats labeled with respective GenBank accessions from CRISPRdb was processed to assign taxonomy information based on GenBank accession. Taxonomy information was extracted from GenBank records with the Perl module Bio::DB::GenBank. Statistics describing the distribution of binomial names or genuses to which individual direct repeats affiliated were compiled with Microsoft Excel.

| Mean | 1.308 | 1.063 |
| Median | 1 | 1 |
| Mode | 1 | 1 |
| Minimum | 1 | 1 |
| Maximum | 46 | 20 |
