摘要

The rationales behind comparing sequences may be manifold. Above all, the theory of evolution tells us that gene sequences may have derived from common ancestral sequences. Thus, the comparison of biological sequences in this context is based on counting the number of mutations, insertions, and deletions of bases necessary to transform one DNA sequence into another.
