| Outline of Final Research Achievements |
By making a ICON a probe which specifically cross-link and bound to the methylated cytosine, probe DNA can specifically hybridize to the target DNA in a sequence dependent manner. By PRINS method, a DNA elongation reaction was established using bounded ICON probe on the specific ch romosome. Modified nucleotides were incorporated during this elongation stem and visualized by a conventio nal histochemical techniques. By this easy, methyalation status of specific chromosome or DNA sequence cou Id be visualized. So far we gathered a lot of basic and fundamental data. \Ve are now currently trying to v isualize a single-copy gene during spermatogenesis in mouse testis, and updating our protocol for more sta ble and reliable one.
