Week 8 Cell Division
Question | Answer |
---|---|
Prophase | 1st and longest phase of mitosis when chromosomes become visible, centrioles separate and take position on opposite sides of the nucleus |
centriole | one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope |
spindle fiber | fanlike microtubule structure that helps separate the chromosomes during mitosis |
Metaphase | 2nd phase of mitosis where the chromosomes line up across the middle of the cell |
Anaphase | 3rd phase of mitosis where the chromosome pairs separate and move toward opposite poles |
Telophase | 4th and final phase of mitosis where the chromosomes begin to disperse into a tangle of dense material (chromatin) |
cell division | process by which a cell divides into two new daughter cells |
chromatid | one of two identical “sister” parts of a duplicated chromosome |
centromere | Area where the chromatids of a chromosome are attached |
Interphase | period of growth between cell divisions |
cell cycle | series of events that cells go through as they grow and divide |
mitosis | part of eukaryotic cell division during which the cell nucleus divides |
