| Term | Definition |
|
mitosis |
part of eukaryotic cell division during which the cell nucleus divides |
|
four phases of mitosis |
prophase, metaphase, anaphase, telophase |
|
prophase |
the chromatin condenses into chromosomes, the centrioles separate and a spindle forms, the nuclear envelope breaks down |
|
metaphase |
chromosomes line up across center of cell, each chromosome is connected to a spindle fiber at its centromere |
|
anaphase |
the sister chromatids separate and are moved apart |
|
telophase |
chromosomes gather at opposite ends of cell and lose their shape, two new nuclear envelopes will form |
|
interphase |
cell grows and replicates DNA and centrioles |
|
cytokinesis |
cytoplasm pinches in half, each daughter cell has an identical set of duplicate chromosomes |
|
centrioles |
two tiny structures located in the cytoplasm and near the nuclear envelope |
|
spindle |
a fanlike microtubule structure that helps seperate chromosomes |
|
centromere |
where the chromatids of a chromosome are attached |
