Cell Cycle Stages
What happens when cells divide with no control? (what can develop?)
What is cancer?
Produced by centromeres; job is to pull sister chromatids apart (aka spindle fibers)
What is microtubules?
The stage of mitosis where the sister chromatids are on opposite poles of the cell and the nuclear membrane reappears.
What is telophase?
What happens during cytokinesis?
Draw metaphase.
Sister chromatids should be lined up in the middle of the cell.
The stage of the cell cycle when DNA replicates.
What is S phase?
One is the original strand of DNA, the other is a copy; they come together to form a chromosome.
What is a sister chromatid?
The stage of mitosis when Chromosomes are lined up on the cell's equator.
What is metaphase?
In plant cells, what forms during this phase?
Draw Anaphase.
The stage of the cell cycle when the cell grows and organelles replicate?
What is G1 phase?
Holds sister chromatids together (the middle).
What is a centromere?
The stage of mitosis when the cell's chromosomes become visible, the nuclear membrane disappears, and the microtubules appear.
What is prophase?
In animal cells, what forms during this phase?
Cleavage furrow
Draw Telophase.
Sister chromatids are on opposite poles of the cell and the nuclear membrane begins to appear.
The stage of the cell cycle that includes G1, S, and G2.
What is interphase?
Contains genetic information that is passed on. Becomes visible during prophase.
What is a chromosome?
The stage of mitosis when sister chromatids are pulled apart.
What is anaphase?
What is the end result of cytokinesis?
2 identical daughter cells
Draw Cytokinesis.
The cytoplasm is splitting. There should be a line down the middle for the cleavage furrow/cell plate.
The stage of the cell cycle when the cell finishes growing and two centrosomes appear in the cytoplasm.
What is the G2 phase?
The attachment site for microtubules on sister chromatids.
What is a kinetochore?
What is the correct order of the phases of mitosis?
What is prophase, metaphase, anaphase, and telophase?
What stage of the cell cycle does a cell go to after cytokinesis?
G1
Draw Prophase.
Nuclear membrane is disappearing. Chromatin condense into chromosomes. Microtubules appear.
