- chromatin fibers become more tightly coiled, condensing into discrete chromosomes
- prophase
- nucleoli disappear
- prophase
- each duplicated chromosome appears as two identical sister chromatids joined at their centromeres and through cohesion
- prophase
- mitotic spindle begins to form
- prophase
- centrosomes move away from each other
- prophase
- nuclear envelope fragments
- prometaphase
- microtubules invade nuclear area
- prometaphase
- chromosomes even more condensed
- prometaphase
- each chromatid has a kinetochore
- prometaphase
- some microtubules attach to kinetochores to become kinetochore microtubules
- prometaphase
- nonkinetochore microtubules interact with those from the opposite pole of the spindle
- prometaphase
- longest stage of mitosis
- metaphase
- centrosomes are now at opposite cellular poles
- metaphase
- chromosomes converge on metaphase plate
- metaphase
- for each chromosome, the kinetochores of the sister chromatids are attached to kinetochore microtubules coming from opposite poles
- metaphase
- shortest stage in mitosis
- anaphase
- cohesin proteins are cleaved
- anaphase
- pair of sister chromatids part suddenly
- anaphase
- chromosomes move toward opposite ends of cell as kinetochore microtubules shorten
- anaphase
- nonkinetochore microtubules lengthen and cell elongates
- anaphase
- nuclei reform
- telophase
- nuclear envelope arises
- telophase
- nucleoli reappear
- telophase
