| A | B |
|---|
| Chromosomes are only visible when ___. | the cell is dividing |
| DNA makes copies of itself (along with the chromosome that it is part of) during ____ | interphase |
| In order, what are the four stages of mitosis? | Prophase, metaphase, anaphase, telophase (remember PMAT) |
| Cell division ends when ___ is finished. | cytokinesis |
| The ____ is a series of events that cells go through as they grow and divide. | cell cycle |
| The ___ is a narrow region of the duplicated chromosome where sister chromatids are attached to each other. | centromere,  |
| The centromere region is where _____ are held together. | sister chromatids, |
| After chromosomes undergo DNA replication, they consist of two identical ____ that are attached to each other. | sister chromatids, |
| During which stages of mitosis are sister chromatids attached to each other? | prophase and metaphase |
| During which stage of mitosis do sister chromatids start to separate? | anaphase |
| During which stage of mitosis are sister chromatids lined up along the middle of the cell? | metaphase (think metaphase = middle) |
| During which stage of mitosis does the nuclear membrane break down? | prophase |
| During which stage of mitosis do the chromosomes condense to become visible? | prophase |
| In animal cells, centrioles help organize a fan-like group of protein called ____ that help pull the chromosomes apart. | spindle fibers |
| The division of the cytoplasm itself is called ___. | cytokinesis |
| During which stage of mitosis are the chromosomes divided into the two opposite ends of the cell and the nuclear membrane re-forms? | telophase |
| Cell division consists of ___ and ___. | mitosis and cytokinesis, 
|
| During normal cell division, a human cell with 46 chromosomes would produce two daughter cells with ___ chromosomes each. | 46 |
| A cell that has 5 chromosomes at the beginning of interphase would have ___ chromosomes at the end of interphase. | 10 (remember they replicate during the S phase which occurs between G1 and G2) |
The structures labeled A are,  | sister chromatids, |
| The structures labeled B are, | spindle fibers, |
The cell shown below shows a cell in _____ of the cell cycle.,  | telophase, |
The cell shown below shows a cell in _____ of the cell cycle.,  | anaphase, |
The cell shown below shows a cell in _____ of the cell cycle.,  | metaphase, |
The cell shown below shows a cell in _____ of the cell cycle.,  | prophase, |
The cell shown below shows a cell in _____ of the cell cycle.,  | interphase, |
| In order, what are the five major stages of the cell cycle? | interphase, prophase, metaphase, anaphase, telophase (Remember the phrase "I pinched Martha's arm today.") |
| Uncontrolled cell division is also known as ______. | cancer |
| When cells divide over and over again because of cancer, a lump of cells called a ____ forms. | tumor |
| Special _____ inside the cell act as "on" switches, or "off" switches, to speed up or slow down the cell cycle as needed. | proteins |
| A ____ can cause the proteins that control cell division to be made incorrectly and malfunction, causing the cell to divide uncontrollably. | mutation in DNA |
| True or false: Interphase is a stage of mitosis. | False (Interphase happens before the stages of mitosis. The stages of mitosis are prophase, metaphase, anaphase, and telophase) |
| True or false: Cytokinesis is a stage of mitosis. | False (Cytokinesis does start during telophase, but it is not a stage of mitosis. The only stages of mitosis are prophase, metaphase, anaphase, and telophase. Cytokinesis is a process that starts to happen during telophase and usually ends shortly after telophase has ended. Cytokinesis is simply the splitting of the cell's cytoplasm into two different cells) |
| True or false: Mitosis is asexual reproduction. | False (Mitosis is part of asexual reproduction in single-celled eukaryotic organisms that divide to form new single-celled organisms that are genetically identical to the parent cell. However, the cells that divide in multicellular organisms including the stages of mitosis are not an example of asexual reproduction because they are not creating a new organisms). |
| A cell that has 5 chromosomes at the beginning of interphase would produce two cells, each having have ___ chromosomes by the end of the cell cycle. | 5 |
| During which stage of mitosis does the nuclear membrane re-form itself? | telophase |
