| Question | Answer |
|---|---|
| Cell Cycle | cells reproduce by a cycle of growing and dividing |
| Chromatin | is the relaxed form of DNA in the cell's nucleus. |
| Chromosome | are the structures that contain the genetic material that is passed from generation to generation of cells. |
| Cytokinesis | is the method by which a cell's cytoplasm divides, creating a new cell |
| Interphase | is the stage during which the cell grows, carries out cellular functions, and replicates, or makes copies of its DNA in preparation for the next stage of the cycle |
| Mitosis | is the stage of the cell cycle during which the cell's nucleus and nuclear material divide |
| Anaphase | - the third stage where the chromatids are pulled apart |
| Centromere | - the structure at the center of the chromosome where the sister chromatids are attached |
| Metaphase | - the second stage of mitosis, the sister chromatids are pulled by motor proteins along the spindle apparatus toward the center of the cell and line up in the middle , or equator, of the cell |
| Prophase | - The first stage of mitosis, the stage of mitosis during which a dividing cell spends the most time |
| Sister Chromatid | - are structures that contain identical copies of DNA |
| Spindle Apparatus | - the whole structure, including the spindle fibers, centrioles, and aster fibers |
| Telophase | - is the stage of mitosis during which the chromosomes arrive at the poles of the cell and begin to relax, or decondense. |
| Apoptosis | - when an embryo divides, some cells go through this process which is a programmed death |
| Cancer | - the uncontrolled growth and division of cells- a failure in the regulation of the cell cycle. |
| Carcinogen | - substances and agents that are known to cause cancer |
| Cyclin | - proteins |
| Stem Cell | - are unspecialized cells that develop into specialized cells when under the right conditions |
