| Question | Answer |
|---|---|
| Cell Divison | the process through which a cell copies itself |
| Cancer | begins when a cell divides although it should not |
| Tumor | a mass of cells with no apparent function in the body |
| Benign Tumors | do not effect surrounding structures |
| Malignant Tumors | do effect surrounding structures |
| Metastasis | when malignant tumors break away and start new cancer elsewhere |
| lymphatic system | collects fluids lost from capillaries |
| lymph nodes | structures that filter lost fluids |
| circulatory system | after they metastasize, cells gain access to this system and the heart, allowing them to travel throuhgout the body |
| asexual reproduction | reproduction with only one organism |
| chromosomes | structures in which DNA is organized inco, which carries hundreds of genes along their length |
| sister chromatid | the copy of a chromosome |
| centromere | what connects the sister chromatid and the original DNA |
| DNA polymerase | adds the correct base to the now single strand of DNA |
| Mitosis | asexual division |
| Interphase | The phase in which most of the cell's life is spent in |
| Prophase | Replicated chromosomes condense. Microtubules form at the poles of the cell. The nuclear envelope disintegrates. |
| Metaphase | Replicated chromosomes line up across equator of cell. Microtubules attach to the centromeres |
| Anaphase | The centromere splits. Microtubules pull sister chromatids apart towards poles |
| Telophase | Nuclear envelopes reform around chromosomes. Chromosomes revert to uncondensed form. |
| Tumor suppressors | genes that carry instructions for producing proteins that stop cell division if necessary |
| Contact inhibition | in normal cells prevents them from dividing all the time, which would force the new cells to pile up on each other |
| Anchorage dependence | in normal cells keeps the cells in place |
| Angiogenesis | growth of blood cells caused by secretions from cancer cells |
| Multiple hit model | describes the process of cancer development |
| biopsy | the surgical removal of cells, tissue, or fluid for analysis is performed |
| chemotherapy | Chemicals that kill dividing cells are injected into the bloodstream |
| radiation therapy | High energy particles damage DNA, so cells can't divide |
| remission | if the patient is no longer suffering negative impacts from cancer after a given period |
| meiosis | Another form of cell division that occurs in the gonads |
| gametes | Meiosis produces sex cells |
| karyotype | is a photograph of chromosomes in pairs |
| homologous pairs | The pairs of chromosomes carry the same genes |
| haploid | having only one of each kind of chromosome |
| diploid | they have two of each kind of chromosome |
| Prophase I | homologous pairs come together |
| Metaphase I | the homologous pairs line up at the equator |
| Anaphase I | the homologous pairs separate |
| Telophase I | nuclear envelopes reform |
| Prophase II | nuclear envelopes disappear |
| Metaphase II | chromosomes line up at the equator |
| Anaphase II | the sister chromatids separate |
| Telophase II | nuclear envelopes reform |
