Figure 5

CyclinB is not degraded in lmg mutants. Colours are the same as in Figure 4. The level of Cyclin B is high in wild-type (n = 24) prophase and prometaphase cells (A and D) and it starts to disappear at or after the onset of metaphase (B and E). Cyclin B staining is quite pronounced in most of the lmgJ023 (C and F) cells (n = 20) arrested in metaphase.
