chapter 15: The Eukaryotic Cell Cycle, Mitosis and Meiosis
-
Mitosis
phases
Prophase
Sister chromatids condense, and the mitotic spindle starts to form. The nuclear envelope begins to dissociate into vesicles. Nucleolus is no longer visible
Prometaphase
The nuclear envelope has completely dissociated into vesicles, and the mitotic spindle is fully formed. Sister chromatids attach to the spindle via kinetochore microtubules.
-
Anaphase
Sister chromatids separate, and individual chromosomes move toward the poles as kinetochore microtubules shorten. Polar microtubules lengthen and push the poles apart.
-
-
meiosis
Like mitosis, meiosis begins after a cell has progressed through the G1, S, and G2 phases of the cell cycle.
-
-
Meiosis II:
No S phase between meiosis I and meiosis II.
Sorting events of meiosis II are similar to those of mitosis.
Sister chromatids separated in anaphase II,unlike anaphase I.
