|
period of the cell cycle between cell divisions |
Interphase |
|
|
division of the cytoplasm during cell division |
Cytokinesis |
|
|
The first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes |

|
|
protein structures which move the chromosomes during cell division |
Spindle Fiber |
|
|
the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle |
Metaphase |
|
|
the stage of meiosis or mitosis when chromosomes move toward opposite ends of the cell, or opposite poles |
Anaphase |
|
|
the final stage of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosomes |
Telophase |
|
|
the precursor of a new plant cell wall that forms during cell division and divides a cell into two |

|
|
the side by side pairing of homologous maternal and paternal chromosomes at the start of meiosis |

|
|
random separation of genes during the formation of gametes |
