Bio Exam two
| Question | Answer |
|---|---|
| Proteins that signal the cell cycle control system to stop cell division or to continue it? | Growth Factiors |
| When cancer has spread through the circulatory system to other parts of the body | metastasized |
| an identical copy of a chromosome | sister chromatids |
| the most common type of cancer in the US | Skin Cancer |
| Skin, organ, and intestinal cancers(such as lunch, breast, prostate, and colon cancer are. | carcinoma |
| The _____ celel cycle control checks to make sure DNA has replicated correctly, forming identical sister chromatids. If not, cell division stops. | G2 Checkpoint |
| The longest stage of the cell cycle, when cell grows and duplicates their chromosomes. | Interphase |
| Once your DNA has condensed from chromatin into ________ mitosis has begun. | Chromosomes |
| When cell divides in an uncontrolled fashion and looks distinctly abnormal. | Displasia |
| The _____ cell cycle control checks to make sure spindle fibers are attached correctly to each sister chomatid. If not, cell division stops. | M Checkpoint |
| this stage of mitosis is essentially the reverse of prophase. | telophase |
| the state of mitosis when spindle fibers pull sister chromatids apart | Anaphase |
| The specific type of cancer that is caused by uncontrolled division of abnormal white blood celles | Leukemia |
| Damaged DNA is referred to as a ______. As a result your DNA does not produce proteins correctly. | mutation |
| the life cycle of a cell | cell cycle |
| the stage of the cell cycle immediately after G2 ( when the cells nucleus divides) | mitosis |
| the stage when spindle fibers attach to each sister chromatid | prophase |
| the stage when sister chromatids line up in the middle of the cell | metaphase |
| a tumor that remains at its original location(where is forms) | benign |
| this carinogen causes more types of cancer and more cases of deadly cancer than any other carcinogen | tobacco |
| during cell division, an animal cell pinches inward to form a _____ this eventually splits the parent ell into two new cells | Cleavage furrow |
| if a cell is in the G1 stage of the cell cycle, your dna is in the form of? | chromatin |
| the stage of the cell cycle when the cytoplasm dvidies, creating 2 new cells | cytokenesis |
| a pair of chromosomes that carry the same types of genes | homologous pairs |
| tiny organelles responsible for making spindle fibers that move chromosomes during mitosis | centrioles |
| because cell division is ________ your cells stop dividing when they come in contact with one another or become crowded | density dependent |
| a photographic inventory of a persons chromosomes | karyotype |
| uncontrolled cell growth in which cells divide repeatedly to produce a mass of cells(a tumor) | hyperplasia |
| a cancer causing agent these are external factors that alter your DNA (cause genetic mutations) | carcinoger |
