During cell division, spindle microtubules attach to chromosomes through kinetochores, protein complexes on the chromosome. The central question is how microtubules find kinetochores. According to the pioneering idea termed search-and-capture, numerous microtubules grow from a centrosome in all directions and by chance capture kinetochores. The efficiency(More)
Pairing of homologous chromosomes is a crucial step in meiosis, which in fission yeast depends on nuclear oscillations. However, how nuclear oscillations help pairing is unknown. Here, we show that homologous loci typically pair when the spindle pole body is at the cell pole and the nucleus is elongated, whereas they unpair when the spindle pole body is in(More)
[Abstract] We use fluorescence recovery after photobleaching (FRAP) to calculate the diffusion coefficient of GFP in the nucleoplasm of fission yeast. The FRAP method can be generally used to measure the mobility of proteins inside the cell or its organelles. In our experiment we only measured the diffusion of GFP inside the nucleoplasm of fission yeast(More)
