Wed. Dec 3, 2025 5:20 AM - 7:20 AM UTC
Room 6(Pacifico Yokohama Conference Center 3F, 311+312)
Organizer: Naomichi Takemata (Ritsumeikan University), Shogo Ozaki (Kyushu University)
The chromosome must be properly compacted, duplicated, and segregated to the next generation in all life forms. Despite this universal task, the underlying mechanism appears to be diverse among bacteria, archaea, and eukaryotes. This symposium will present the latest research findings on chromosome dynamics in the three domain of life, discussing the universal principles and diversity underlying genetic systems.
