33 T he prevailing method of determining the sequence of a long DNA segment is the shotgun sequencing approach, in which a random sampling of short fragment sequences is acquired and then assembled by a computer program to infer the sampled segment's sequence. In the early 1980s, such segments were typically on the order of 5,000 to 10,000 base pairs (5 to 10 kbp). By 1990, this method was sequ...
