Mitosis or Meiosis and Cell Cycle
| Question | Answer |
|---|---|
| Produces two genetically identical daughter cells | mitosis |
| regeneration | Asexual reproduction (mitosis) Regrow a missing part of the body |
| Produces four genetically unique daughter cells | meiosis |
| budding | Asexual reproduction (mitosis) New organism grows on the body of its parent and then detaches |
| egg and sperm fertilization | sexual reproduction meiosis |
| 2n --> 2n | mitosis |
| 2n --> n | meiosis |
| start with one diploid cell copy DNA pull sister chromatids apart form two identical diploid daughter cells | mitosis |
| start with one diploid cell homologous chromosomes in tetrads crossing over and pulled apart two unique haploid cells haploid sister chromatids pulled apart form four unique haploid daughter cells | meiosis |
| fragmentation | Asexual reproduction (mitosis) Parent breaks into parts that regenerate into whole new individuals. |
| vegetative propagation | Asexual reproduction (mitosis) Plants produce genetically identical offshoots of themselves, which then develop into independent plants |
| gametes | egg and sperm meiosis |
| grow and repair | mitosis |
| asexual reproduction | mitosis |
| two parents | sexual reproduction meiosis |
| one parent | asexual reproduction mitosis |
| creates genetic variation during prophase I (crossing over) and metaphase I (random assortment) | meiosis |
| two cell divisions | meiosis |
| one cell division | mitosis |
| sexual reproduction | meiosis |
| identical copies/clones created | mitosis |
| Interphase | G1 phase, S phase, G2 phase 90% of cell life |
| M phase | cell division mitosis or meiosis PMAT 10% of cell life |
| G1 | new growth |
| S phase | replicate/copy the DNA |
| G2 | final growth |
| chromatin | loose strand of DNA DNA form during Interphase |
| chromosome | condensed strand of DNA DNA form during M phase |
| nondisjunction | the failure of chromosomes to separate normally during nuclear division, usually resulting in an abnormal number of chromosomes in a daughter cell |
| apoptosis | programmed cell death; cell destructs itself |
