07. Mitosis

What happens during Prophase?

Chromosomes condense and become visible.

What happens to the nuclear envelope during Prophase?

The nuclear envelope breaks down.

What begins to form during Prophase?

The mitotic spindle begins to form.

In Prophase, where do the spindle microtubules extend from?

The centrosomes.

In Prophase, where do spindle microtubules extend to?

The chromosomes.

In Prophase, what is the main purpose of the mitotic spindle?

To help move and separate chromosomes during mitosis.

What happens to chromosomes during Metaphase?

Chromosomes line up at the equator of the cell.

What is the metaphase plate?

The line at the equator of the cell where chromosomes align.

What aligns on the metaphase plate?

The centromeres of the chromosomes.

In Metaphase, what do spindle fibers attach to?

The kinetochores on each chromosome.

In Metaphase, where are the kinetochores located?

At the centromere of each chromosome.

What happens during Anaphase?

The spindle fibers pull the sister chromatids apart.

Where are the sister chromatids pulled during Anaphase?

Each chromatid is pulled toward opposite poles of the cell.

In Anaphase, what pulls the sister chromatids apart?

Spindle fibers.

In Anaphase, Where do the separated chromatids move?

Toward opposite poles of the cell.

What happens during Telophase?

Chromosomes reach the poles of the cell and begin to decondense.

What happens to the nuclear envelope during Telophase?

The nuclear envelope reforms around each set of chromosomes.

What happens to the spindle fibers during Telophase?

The spindle fibers begin to break down.

Where do the chromosomes go during Telophase?

They reach opposite poles of the cell.
