| Question | Answer |
|---|---|
| in interphase what is the step says cell grows producing organelles | G1 |
| in interphase what is the step that says DNA is copied | S |
| in interphase what step says continue growth | G2 |
| list the phases of the cell cycle in order | interphase,prophase,metaphase,anaphase,telophase,cytokenesis |
| when are the chromosomes copied during the cell cycle? | S of interphase |
| Which of the following is not a part of mitosis?prophase,metaphase,interphase,telophase,anaphase | G1 of interphase |
| which organelles would be needed to be copied before beginning mitosis? When would this occur? | all G1 |
| During which part of the cell cycle does the cell spend most of its time? | interface |
| In prophase, name the 5 steps in order. | 1. chromatin condenses to form chromatids and homologous chromatids pair together to form a chromosome.2. nucleolis disappears3. nuclear membrane disappears4. centrioles begin to move to opposite poles5. spindle fibers begin to form between the centrioles |
| Why does the nucleolis disappear? | the cell is splitting and is going to make a new cell |
| ____________ is the first and longes phase of mitosis. | prophase |
| the oppostite ends of the cell are called ____________ | poles |
| The _________________ organize the spindle | centrioles |
| the last phase of mitosis is ______________ | telophase |
| _____________ is the shortest phase of mitosis | metaphase |
| The process of copying chromosomes is called _____________ | replicating |
| The third phase of of mitosis is called _____________ | anaphase |
| during prophase the nuclear membrane _____________ | disappears |
| true or false the only step in metaphase says that chromosomes line up at the equator of the cell | True |
| why would it be necessary to line up chromosomes in one place? | so they can all split at the same time |
