Nuclear Division
Cell type: (MI) mitosis
Component: Nuc Div / SPB
| Characteristic | State | Code | Images |
|---|---|---|---|
| Centriole | present | 1 |  |
| Basic organization of the spindle pole | centriolar-associated material | 0 | |
| Spindle pole body form, interphase-prophase | centriole-associated material | c | |
| Spindle pole body form, metaphase-anaphase | centriole associated material | f | |
| Spindle development site | gap in nuclear envelope | 0 | |
| Spindle pole body migration (per Heath, 1980, Int. Rev. Cytol. 64:1) | migration before spindle formation | 0 | |
| Metaphase nuclear envelope | loose polar fenestrae, including extensions of nuclear envelope into the cytoplasm at the spindle pole, but mainly intact | 2 | |
| Telophase nuclear envelope | retention of complete nuclear envelope around the chromatin with median constriction/fragmentation | 0 | |
| Perinuclear endoplasmic reticulum | absent | 0 | |
| Central spindle | absent | 0 | |
| Metaphase plate | present | 1 | |
| Spindle pole body cap | absent | 0 | |
| Nucleolus behavior | nucleolus or part of it is more persistent and is discarded after metaphase | 2 | |
| Transient intranuclear element at late interphase-prophase | absent | 0 | |

| Notes | Nucleolus is expelled at telophase. A dictyosome is associated with the centriole early in mitosis. |
