| mitosis | division of the nucleus |
| cytokinesis | division of the cytoplasm |
| Chromatin | long thin strands of genetic material located in the nucleus of the normal cell. |
| Prophase | chromatin in the nucleus condenses to form chromosomes; spindle fibers begin to form; the nuclear membrane disappears and the nucleolus disappears. |
| Metaphase | The chromosomes line up across the center of the cell (equator). Each chromosome attaches to a spindle fiber at its centromere. |
| Interphase | The cell grows to its mature size (G1); makes a copy of its DNA (S); and prepares to divide into two cells (G2). |
| Anaphase | The centromeres split and the sister chromatids separate and move to opposite ends of the cell. |
| Telophase | The chromosomes begin to stretch out and become chromatin; a new nuclear membrane forms around each mass of chromosomes; the nucleolus begins to reappear. |
| Cytokinesis | The cell membrane pinches in around the middle of the animal cell; a cell plate forms in the middle of plant cells the cell splits into two; each daughter cell is identical to the original parent cell. |
| When is the DNA of the cell copied? | During the S phase of Interphase. |
| What are the phases of mitosis? | Prophase; Metaphase; Anaphase; and Telophase |
| What is the period of growth and development of the cell called? | Interphase (G1, S and G2) |
| How many chromosomes does a human have? | 46 chromosomes |
| At the end of the S stage of Interphase, how many chromosomes does a human cell have? | 92 chromosomes |
| The duplicated chromosomes are called what? | Sister Chromatids |
| The sister chromatids are held together at the ???? | Centromere |
| Most of the life of the cell is spent in | Interphase |
| The purpose of mitosis is for | growth and to replace dead or damaged cells |
| Binary Fission | The process of reproduction in prokaryotic cells |
| centrioles | the structures in animal cells that make the spindle fibers. |
