HBio Cell Cycle
Question | Answer |
---|---|
Part of the cell cycle where the cell will perform its function. It includes the stages G1, S, and G2. | Interphase |
Part of the cell cycle where the cell's genetic material divides. | Mitosis |
Part of the cell cycle when the cytoplasm divides forming 2 identical daughter cells. | Cytokinesis |
Part of Interphase when the cell grows BEFORE the DNA is copied. | G1 |
Part of Interphase when the DNA is copied (new copy is Synthesized). | S-phase |
Part of Interphase when the cell grows AFTER the DNA is copied. | G2 |
What are the 4 phases of Mitosis in order? | Prophase, Metaphase, Anaphase, Telophase |
1st stage of mitosis; the nuclear envelope disappears and chromosomes condense. | Prophase |
2nd stage of mitosis; sister chromatids line-up down the cell equator (in the middle). | Metaphase |
3rd stage of mitosis; sister chromatids are pulled apart to different poles of the cell. | Anaphase |
4th stage of mitosis; the nuclear envelope reforms, chromosome decondense (uncoil) and the cell begins to divide. | Telophase |
Part of the cell that aids in cell division. | Centrioles |
DNA/protein structure in its condensed form. | Chromosomes |
A chromosome and its copy (makes an "X" shape). | Sister Chromatids |
String-like structures coming from the centrioles that attach to the chromosomes to pull them apart. | Spindle fibers |
Site where the cell pinches in during Telophase. | Cleavage furrow |
First seen in plant cells during Telophase, part of the cell that becomes a new cell wall. | Cell plate |
Site on a chromosome where the sister chromatids are connected and the spindle fibers attach. | Centromere |
Decondensed or uncoiled DNA and protein structure. | Chromatin |
