| 214 | 214 | ||cut7||In the temperature-sensitive cut7 mutant, spindle formation is blocked shortly after duplication of the SPB. The mitotic spindle radiating from the opposite poles cannot interdigitate and thus remains as a V shape (Hagan and Yanagida, 1992). The cut7- specific defect generates a condition whereby the bipolar attachment of the spindle to kinetochores is not achieved. Previously, we demonstrated that this defect causes an arrest in a mad2+-dependent manner (Kim et al., 1998). At the restrictive temperature the majority of Mad2-GFP was found on condensed chromosomes as one or more speckles (Fig. 4).|| |
