Alignment Problem

Alignment Problem. (Optimal) pairwise alignment consists of considering all possible alignments of two sequences and choosing the optimal one. Sub-optimal (heuristic) alignment algorithms are also very important: e.g. BLAST. Key Issues. Types of alignments (local vs. global)

The Human Genome

The Human Genome. Since it began in 1990, the Human Genome Project is estimated to have cost $3,000,000,000. The Human Genome. The vast majority of DNA in the human genome -- about 97 percent -- consists of non-genetic sequences with unknown function, sometimes called "junk DNA.".
