Men love to wonder, and that is the seed of science.
The map is then assembled by putting together tens of thousands of random DNA fragments of similar size. These pools of fragments are used instead of individual fragments in order to reduce the number of screenings that must occur. The results of these pool screenings may be remapped into individual fragment screening results. To construct the map from DNA screening results, fragments which match the same STS are first grouped. The last step is to arrange the fragments within the groups, thereby producing an ordered physical map.
