| the stage of the cell cycle during which genes are copied. | interphase |
| When a chromosome has been duplicated and the copies are still attached | the structures that contain the copies are called |
| flatworm that can reproduce through regeneration | planarian |
| the process made up of mitosis and cytokinesis | cell division |
| the process that equally distributes the cell's chromosomes between two new daughter cells. | mitosis |
| the phase of mitosis when new nuclear membranes form | telophase |
| the phase when the nuclear membrane disappears | prophase |
| the chromosomes are lined up in the middle of the spindle. | metaphase |
| the phase of mitosis when the daughter chromosomes move toward opposite sides | anaphase |
