Mitosis[edit]
- Prophase: breakdown of the nuclear envelope is independent of microtubule assembly from the microtubule organizing center is separate from breakdown of the nuclear envelope which is complete at prometaphase
- Spindle checkpoint separates metaphase from anaphase
- Anaphase promoting complex

Cell junctions[edit]
- adherens junctions (zonula adherens) linked to actin filaments
- desmosomes (macula adherens) - linked to intermediate filaments
- gap junctions - small molecule intercellular transport
- tight junctions (zona occludens) - linked to actin filaments
- hemi-desmosomes - linked to intermediate filaments
- focal adhesions - linked to actin
