 interphase |  chromosomes double, (46-92) 16 hours |
| prophase I |  nuclear envelope & nucleoli disappear; mitotic spindles form; chromosomes pair off; crossing over occurs. |
| metaphase I |  pairs of chromosomes line up along middle |
| anaphase I |  paired chromosomes move apart |
| telophase I |  two cells containing 23 pairs of chromosomes each; cytokinesis. |
| prophase II |  1 what phase is this? |
| metaphase II | 2 what phase is this? |
| anaphase II |  what phase is this? |
| telophase II |  what phase is this? |
| chromosome |  name this whole structure. coiled structure of DNA and protein found in cells. It appear to be dots, but are really solid lines. |
| sister chromatids |  what are the two identical structures? |
| centromere | red circle |
| mitotic spindles |  white arrow the structure that separates the chromosomes into the daughter cells during cell division. |
| aster | yellow arrow star shaped anchors, located at opposite ends of the cell that pull the chromosomes apart, allowing the cell to divide. |
| centrioles | black arrow |
| crossing over | what are the chromosomes doing? |
| cytokinesis | division of cytoplasm (cytosol and organelles) into two identical cells. Starts in anaphase and finishes at completion of telophase. |
