The law of bankruptcy and security interests the entire alignment matrix to find what amounts to one long exact match. It might be quicker to first look for exact matches and build alignments from them. As we shall see in Chapter 4, this is the approach used in modern alignment tools like Blast. This means that exact matching, the topic of th

Then we move to the best known application of fast alignment, local alignment between a short query and a long subject as implemented in Blast.

We already saw that phylogenies in the form of guide trees are useful for computing multiple sequence alignments. But beyond clever computing, phylogenetic trees embody biologists’ thinking, taxonomies are trees and evolution is p

One aspect of data analysis rarely mentioned is that we can only compute with data stored in a suitable format. The emphasis on human-readable text in Unix is already very helpful, but as we s

Evolution within Populationsons, which might eventually become unable to interbreed. One species has split in two. The differences within species are the subject of population genetics. Here the descent of genes takes center stage. This is often modeled using yet another tree, the coalescent.
