| Question | Answer |
|---|---|
| Chromosome: | A threadlike structure within the nucleus of a cell that contains genetic information that gets generationally passed on |
| Chromatin: | A substance found in eukaryote chromosomes that consists of DNA tightly coiled around histones |
| Interphase | The period of the cell cycle between cell divisions when the cell grows. |
| Mitosis | the process by which the nucleus divides. |
| Centriole | A structure in an animal cell that helps to organize cell division |
| Centromere: | The region of the chromosome where the two sister chromatids attach. |
| Chromatid | One of the two identical sister parts of a copied chromosome. |
| Prophase | The first and longest part of mitosis is when the genetic material inside the nucleus of the cell condenses and the chromosome becomes visible. |
| Metaphase | The place of mitosis where the chromosomes line up across the center of the cell. |
| Anaphase | The phase of mitosis when the chromosomes separate and move to opposite ends of the cell. |
| Telophase: | The phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin. |
| Cytokinesis | division of the cytoplasm |
| Cancer: | A disorder in which some of the body's cells lose the ability to control growth |
| Tumor: | A mass of rapidly dividing cells that can damage surrounding tissue. |
| Benign Tumor: | A tumor that stays in its primary location without invading other sites of the body. |
| Malignant Tumor: | A tumor that has cells that grow uncontrollably, the cells are spread locally or to distant sites. |
| Metastasis | The development of secondary malignant growths at a distance from a primary site of cancer. |
| Stem Cell: | An unspecialized cell that can give rise to one or more types of specialized cells. |
