Table 1
Mutations can vary by eight orders of magnitude
| Scale | Nature |
|---|---|
| <0.1 bp | Methylation (5methylC → C) |
| 1 bp | Transitions, transvertions (A → G, C → T, etc) |
| 1–10 bp | Deletions, insertions, deletion–insertions |
| 10–102 bp | Deletions, insertions, invertions, duplications |
| 102–103 bp | Whole exon(s) ±intron(s) |
| 103–105 bp | Whole gene |
| 106–107 bp | Contiguous arrays of genes |
| 107–108 bp | Segments/whole chromosomes |
