Cellular Division
Mitosis
-
-
Process
-
-
Prometaphase- Mitotic spindle is fully formed and they interact with sister chromatids via kinetochore microtubules. Nuclear envelope completely dissociates.
-
Prophase- Sister chromatids condense.
Nuclear envelope begins to dissociate into small vesicles
Nucleolus is no longer visible.
Meiosis
-
-
Process
-
-
Telophase I- The chromosomes decondense, nuclear envelope re-appears and the 2 daughter cells are seperated (cytokinesis).
-
-
-
Metaphase I- Bivalents align along the metaphase plate, each pair of sister chromatids attached to one pole.
-
Prometaphase I- The nuclear envelope completely dissociates and bivalents become attached to kinetochore microtubules.
Prophase I- Homologous chromosomes synapse to form bivalents, and crossing over occurs. Chromosomes condense, and the nuclear envelope begins to dissociate into vesicles.

Interphase
S
Each chromosome is replicated to form a pair of chromatids. Human cells will have 46 chromosomes but 92 chromatids.
