Mitosis and Meiosis
Review of Meiosis and Mitosis
| Question | Answer |
|---|---|
| 2 divisions & 8 phases | Number of cell divisions and phases in meiosis |
| 1 division & 4 phases | Number of cell divisions and phases in mitosis |
| somatic cells | cells that go through mitosis |
| sex cells | cells that go through meiosis |
| diploid | means "2 sets" ; 2n |
| haploid | means "1 set" ; 1n |
| mitosis | process that creates 2 identical diploid cells |
| meiosis | process that creates 4 genetically different haploid cells |
| cytokinesis | division of the cytoplasm |
| 4 sperm | results of meiosis in males |
| 1 egg & 3 polar bodies | results of meiosis in females |
| centromere | holds 2 sister chromatids together |
| 23 | haploid number in humans |
| 46 | diploid number in humans |
| cytokinesis | division of the cytoplasm |
| G1 and G2 phases | cell growth happens |
| S phase | DNA gets copied |
| Interphase | is made up of G1, S and G2 phases (chromosomes look stringy) |
| prophase I | when crossing over happen in meiosis |
| metaphase I | when independent assortment happens in meiosis |
| anaphase II | when sister chromatids are separated |
| anaphase I | when homologous chromosomes are separated |
