is the first stage.
chromosomes condense and become visible.
Spindle fibers emerge from the Centrosomes.
nuclear envelope breaks down
nucleolus disappears

Image: Prophase

second stage of mitosis.,
chromosomes continue to condense
kinetochores appear at the centromeres
mitotic spindle microtubules attach to kinetochores
centrosomes move toward opposite poles

Image: Prometaphase

third step in mitosis.
mitotic spindle is fully developed, centrosomes are at opposite poles of the cell
chromosomes are lined up at the metaphase plate
each sister chromatid is attached to a spindle fiber originating from opposite poles
Chromosomes are all in the middle

Image: Metaphase

fourth step in mitosis.
cohesin proteins binding the sister chromatids together break down
sister chromatids (now called chromosomes) are pulled toward opposite poles
non-kinetochore spindle fibers lengthen, elongating the cell

Image: Anaphase

is the fifth step in mitosis.
chromosomes arrive at opposite poles and begin to decondenese
nuclear envelope material surrounds each set of chromosomes
the mitotic spindle breaks down

Image: Telophase

is the sixth and final step of mitosis.
Animal cells: a cleavage furrow separates the daughter cells
Plant cells: a cell plate separates the daughter cells
The division of cytoplasm that forms the two separate daughter cells

What is the correct order of mitosis?

prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis.

What does the following passage describe?: The kinetochores appear at the centromeres, the mitotic spindle microtubules attach to kinetochores, and the centrosomes move toward opposite poles.

prometaphase, the second step in mitosis

What occurs during anaphase?

Sister chromatids (or chromosomes) are pulled toward opposite poles

The correct order of events in mitosis?

The kinetochore becomes attached to the mitotic spindle. Sister chromatids line up at the metaphase plate. Cohesin proteins break down and the sister chromatids separate. The nucleus reforms and the cell divides.
