What is mitosis?

Mitosis is part of the cell cycle where parent cell divide to create two identical daughter cells.

Does mitosis refer to the separation of the duplicated genetic material carried in the nucleus? (DNA)

Yes, during the cell division, the cell duplicates its DNA and then it is divided between the two new cells.

Why is mitosis important for your body?

Because without it, our cells wouldn't be able to duplicate and we wouldn't grow or repair ourselves.

What are chromosomes made out of?

Protein and DNA.

How many chromosomes are in each cell?

46.

What makes up tissue?

Cells.

What makes up an organ?

Tissue.

What makes up an organ system?

Several organs.

What makes up an organism?

Several organ systems.

What does PMAT stand for?

Prophase, Metaphase, Anaphase and Telephase.

What is prophase?

The first stage of mitosis division. The nucleus is still there, the cell is still intact and the chromosomes are condensing.

What is metaphase?

The second stage of mitosis division. The chromosomes line up in the middle of the cell (think M for middle), the nucleus is no longer there.

What is anaphase?

The third stage of mitosis division. The chromosomes move away (think A for away) and the sister chromatids are separated. The chromosomes move to opposite ends of the cell and go to the poles of the cell. They move by being connected to spindles (fibers) which are connected to the centriole.

What is telophase?

Telophase is the last step in mitosis division. The chromosomes are on complete opposite ends now, and new nuclei are forming. The nuclei are starting to surround the chromosomes on each side of the cell. (Think T for two because the goal is two new cells)

What is cytokinesis?

Cytokinesis is responsible for splitting the cytoplasm in half when in the mitosis phase. This is done after PMAT is complete.
