Evolutionary changes
- DNA sequences typically change very slowly
- e.g. 2*10-9 /base/year
- changes are not equally likely to persist everywhere
- some genomic regions may be mutated repeatedly while others remain unchanged.
- nucleotide changes are not equal likely
- Transitions (interchanges of purines (A⇔G) or of pyrimdines (C⇔T)) are more likely
- Transversions (interchanges between purines and pyrimdines) are less likely
