Bio Mitosis

List the stages of mitosis in order

interphase, prophase, metaphase, anaphase, telophase

What observations did you make during the animation from interphase back to interphase again?

Varies, student should describe one cell dividing and parts of that cell duplicating and separating.

Through ————- , —————-cells distribute genetic material to daughter nuclei. —————- divides the ————— and distributes organelles to the ——- newly formed ————- cells.

Mitosis, eukaryotic, cytokinesis, cytoplasm, two, daughter

Each ————— strand was replicated earlier during the —————- of the —————— to form two ————— strands called ————————-. These chromatids are held together by —————

DNA, S-phase, interphase, identical, sister chromatids, centromere

During metaphase the nuclear membrane has —————- disintegrated. The ——————— reach the centromeres and align the sister —————— along the center of the cell.

Completely, spindle fibers, chromatids

During prophase, the sister chromatids ————— and supercoil and become————— for the first time during the cell cycle. The —————————- begins to disintegrate. The —————— replicate and move away from each other due to micro tubular action.

Mitosis produces ONLY what type of cells?

Body cells

Why is it important that during mitosis, your cells only make identical cells?

You want to make sure that you have identical cells to replace what was lost

What cell organelle holds your DNA and why is DNA important?

The nucleus holds our DNA and it is important because it holds our genetic information

What two things are chromosomes made of?

DNA and protein

How many chromosomes do our body cells contain?

46

Prophase

Nucleus is still present and chromosomes condense and are visible.
"Pro" means first

Metaphase

Chromosomes line up in the middle of the cell and the nucleus is no longer there.
"M" for middle, chromosomes align in the middle of the cell

Anaphase

Chromosomes move away to opposite sides (poles) of the cell. Move by the help of spindles.
"A" for away; chromosomes are moving away from the center of the cell

Telophase

Chromosomes are at opposite ends and new nuclei surround the chromosomes.
"T" for two; two new nuclei are formed and end goal is 2 new cells.

Cytokinesis

Cytoplasm is split to create two separate cells.
"C" if for cytoplasm splitting

What is the uncoiled stringy DNA in interphase called?

Chromatin
