The object of our current grant is to develop novel methods for mapping of the human genome. The techniques to be assessed were: (1) three methods for the production of unique sequence clones from the region of interest; (2) novel methods for the production and separation of multi-megabase DNA fragments; (3) methods for the production of physical linking clones'' that contain rare restriction sites; (4) application of these methods and available resources to map the region of interest. Progress includes: In the first two years methods were developed for physical mapping and the production of arrayed clones; We have concentrated on developing rare- cleavage tools based or restriction endonucleases and methylases; We studied the effect of methylation on enzymes used for PFE mapping of the human genome; we characterized two new isoschizomers of rare cutting endonucleases; we developed a reliable way to produce partial digests of DNA in agarose plugs and applied it to the human genome; and we applied a method to double the apparent specificity of the rare-cutter'' endonucleases.
