Description:
I sat in the nearly silent library, poised above a dingy-looking keyboard. "Time to make some flashcards for my biology vocab quiz!" I thought. And here it is: vocabulary about interphase and mitosis!

Terms | Definitions |
|---|---|
 centrioles | tiny structures in animal cells that help to organize microtubules |
| cyclin | protein that regulates the cell cycle in eukaryotic cells |
| interphase | phases of the cell cycle that occur between cell divisions; made up of the G1 (gap), S (synthesis), G2 (gap 2), and M (mitosis) phases |
| prophase | first and longest phase of mitosis in which centrioles appear and move to opposite ends of the cell, forming a mitotic spindle |
| metaphase | second phase of mitosis in which the chromatids line up at the center of the nucleus and attach to the spindle fibers |
| anaphase | third phase of mitosis in which the chromatids are pulled away from each other by the spindle fibers |
| telophase | final stage of mitosis in which a nuclear membrane forms around each set of chromosomes. They appear as chromatin, threads rather than rods. |
| mitotic spindle | An assemblage of microtubules and associated proteins that is involved in the movements of chromosomes during mitosis. |
| sister chromatids | identical copies of a chromosome; full sets of these are created during the S(DNA replication) subphase of interphase |
| chromosome | a threadlike body in the cell nucleus that carries the genes in a linear order |
| cell cycle | period from the beginning of one cell division to the beginning of the next |
| cancer | disease in which some of the body's cells grow uncontrollably |
| centromere | area where the two sister chromatids are connected to form a chromosome |
| cytokinesis | process in which the cytoplasm of a cell divides; in animal cells, 'furrowing' occurs; in plant cells, the cell plate forms to make a new cell wall. |
| mitosis | Process of cell divison in eukaryotic cells |
