Selection of DNA Markers

Given a genome, i.e., a long string over a fixed finite alphabet, the problem is to find short (dis)similar substrings. This computationally intensive task has many biological applications. We first describe an algorithm to detect substrings that have edit distance to a fixed substring at most equal to a given e. We then propose an algorithm that finds the set of all substrings that have edit distance larger than e to all others. Several applications are given, where attention is paid to practical biological issues such as hairpins and GC percentage. An experiment shows the potential of the methods.
