| cell division | the process by which a cell divides into two new daughter cells |
| chromatid | well before cell division, each chromosome is replicated into two idential sisters, this is called _______ |
| centromere | this is where each pair of chromatids is attached. This area is usually located near the middle of the chromatids. |
| interphase | this is the in-between time beteeen when cells divide. In other words a cell divides, then, before it divides again, it is called this. |
| cell cycle | a series of events that cells go through as they grow and divide |
| mitosis | this is when the division of the cell nucleus and cytokinesis takes place. |
| prophase | this is the first and longest phase of mitosis, during this phase, the chromosomes become visible |
| centriole | two tiny structures located in they cytoplasm near the nuclear envelope, separate and take up positions on opposite sides of the nucleus |
| spindle | a fanlike microtubule structure that helps separate the chromosomes |
| metaphase | this is the second phase of mitoosis, during this phase, the chromosomes line up across the center of the cell. Microtubules connect the centromere of each chromosome to the poles of the spindle |
| anaphase | this is the third phase of mitosis, the centromeres that join the sister chromatids separate, allowing the sister chromatids to separate and become individual chromosomes |
| telophase | the fourth and final phase of mitosis, the chromosomes, which were distinct and condensed, begin to disperse into a tangle of dense material |
| cytokinesis | this is all that remains to complete the M phase after mitosis. As a result of mitosis, two nuclei are formed usually within the cytoplasm of a single cell. Now, the division of the cytoplasm itself. This step usually occurs at the same time as the telophase. |
| cyclins | regulate the timing of the cell cycle in eukaryotic cells |
| cancer | is a disorder in which some of the body's own cells lose the ability to control growht, as a result, they form masses of cells called tumors that can damage surrounding tissues |
