Cell Cycle
Cell Cycle/Mitosis
Term | Definition |
---|---|
Cell Cycle | Regular sequence of growth and division that cells undergo |
Cancer | A disease in which abnormal cells divide uncontrollably |
Interphase | Longest part of the cell cycle (G1, G0, S, G2) |
G1 | Cell grows and new organelles form |
G2 | Prepares for m phase and nuclear division |
S | DNA Replication |
What does PMAT stand for? | Prophase, Metaphase, Anaphase, Telophase |
Prophase | Chromosomes become visible; nuclear envelope dissolves; centrioles and spindle fiber form |
Centromere | The center piece that holds sister chromatids together |
Metaphase | Sister chromatids line up in the middle |
Anaphase | The spindle fiber pulls the sister chromatids apart forming individual chromosomes |
Telophase | Nuclear envelope forms; spindle fiber dissolves |
Cytokinesis | Cytoplasm divides |
How many daughter cells are made during the cell cycle? | 2 |
Are the cells identical or different? | Identical |
Number of chromosomes for humans | 46 |
diploid | 2n |
haploid | n |
spindle fiber | pulls sister chromatids apart to form individual chromsomes |
What type of reproduction uses mitosis? | asexual |
somatic cells | body cells (all cells other than egg and sperm) |
