Answer:

Prophase: Chromosomes become visible as paired chromatids and the nuclear envelope disappears

Metaphase: Sister chromatids are aligned in the middle

Anaphase: Chromatids are split apart and move toward opposite ends.

Telophase: Reverse of prophase and mitosis ends.

Step-by-step explanation:

More: (If the answer was too breif)

Prophase

• Chromatin condenses into

chromosomes

• Appear as sister chromatids

• Nucleoli disappear

• Mitotic spindle begins to form

• Centrosomes begin to move to opposite ends

• Nuclear envelope begins to breakdown or fragment

Metaphase:

• Centrosomes at opposite ends and mitotic spindle

fully formed

• Sister chromatids (chromosomes) align across

the middle and spidle are attached to both sides

Anaphase:

• Sister chromatids (chromosomes) are split apart and move away toward opposite ends

• Cytokinesis begins during the later stages of anaphase

• Cleavage furrow develops when cytokinesis begins

Telophase:

• Chromosomes become less condensed

• Spindle disappears

• Nuclear envelope forms

• Mitosis ends

• Two daughter nuclei have formed

• Cytokinesis continues

• Usually finishes after telophase
