| mitosis | process where the nucleus of the cell divides into two new nuclei and has the same number of chromosomes as the parent cell. |
| chromosomes | contain the genetic information, DNA, which is passed from generation to generation. |
| sister chromatids | each chromosome contains 2 identical chromatids |
| centromere | structure that holds sister chromatids together |
| prophase | longest phase of mitosis |
| prophase | Which phase takes up 50-60% of total time required? |
| prophase | chromosomes become visible in which phase? |
| prophase | which phase has the centrioles separate and go to opposite poles |
| prophase | the sentromeres become attached to fibers in the spindle, which help separate the chromosomes in which phase? |
| prophase | in which phase does the nucleus disappear and the nuclear envelope breaks down? |
| Metaphase | 2nd and shortest phase of mitosis |
| Metaphase | in which phase do the chromosomes line up at the equator of the cell |
| anaphase | in which phase does the centromeres split and the sister chromatids separate and become individual chromosomes. |
| anaphase | 3rd phase of mitosis |
| telophase | last phase of mitosis |
| telophase | in which phase do the chromosomes untangle into chromatin |
| telophase | in which phase does the nuclear envelope reform and the nucleus becomes visible. |
