mmf Q2 mitosis and meiosis
| Question | Answer |
|---|---|
| what is mitosis? | cell division |
| what are the steps of mitosis in order? | interphase, prophase, metaphase, anaphase, telephase, cytokinesis |
| interphase | cell does life functions- %90-95 of life |
| prophase | nuclear envelope dissipates, all chromosomes are around, spindles form |
| metaphase | all of the chromosomes line up in the middle of cell |
| anaphase | chromosomes pull apart to either side of cells |
| telephase | forming two cells, just connected together |
| cytokinesis | 2 new cells are made |
| what are the steps ,in order, of meiosis? | prophase 1, metaphase 1, anaphase 1, telephase 1, prophase 2, metaphase 2, anaphase 2, telephase 2, cytokinesis |
| what is meiosis? | creation of sex cells |
| prophase 1 | same a mitosis |
| metaphase 1 | chromosomes go with homologues pair in center of cell |
| anaphase 1 | one chromosome of pair and its copy goes one way and the other on the opposite side. |
| telephase 1 | same as mitosis but 23 chromosomes in each cell |
| prophase 2 | same as mitosis |
| metaphase 2 | same as mitosis |
| anaphase 2 | same as mitosis |
| telephase 2/ cytokinesis | spindles go, nuclear envelope comes. 4 sex cells are made |
