100
Cell cytoplasm divides.
What is Cytokinesis?
100
Thread-like DNA seen in interphase.
What is Chromatin?
100
Chromosomes condense into chromatids, and the nuclear membrane breaks down.
What is prophase?
100
Cells produced by mitosis.
What is two?
100
Plant cells develop this during cytokinesis.
What is a cell plate?
200
DNA replicates.
What is interphase or S phase?
200
One half of a duplicated chromosome.
What is a sister chromatid?
200
Sister chromatids are pulled away from each other by spindle fibers.
What is anaphase?
200
Number of times a cell divides during the cell cycle?
What is once?
200
Animal cells develop this during cytokinesis.
What is a cleavage furrow?
300
The stage that includes G1, S, and G2.
What is Interphase?
300
Holds two sister chromatids together at their center
What is a centromere?
300
Sister chromatids line up in the middle of the cell.
What is metaphase.
300
If a parent cell has 46 chromosomes, each of its daughter cells will have this many chromosomes.
What is 46?
300
Examples of this include UV rays, tobacco smoke, and X-rays
What are carcinogens?
400
Cell grows and makes more proteins and organelles.
What is G1 and G2?
400
Chromosome structure that becomes visible during prophase and is shaped like an "X"
What is a chromatid?
400
The nuclear membrane re-appears, and cytokinesis begins.
What is Telophase?
400
Number of chromosomes in humans AFTER interphase.
What is 92?
400
Clumps of cells that can be malignant or benign.
What are tumors?
500
Cells spend most of their life in this phase.
What is interphase?
500
Nucleic acid that makes up most of a chromosome.
What is DNA?
500
Spindle fibers come from this organelle.
What are centrioles?
500
The number of chromatids in a chromosome.
What is 2?
500
When cells have lost their ability to control the cell cycle.
What is Cancer?
