front 1 1. prophase ( 92 chromosomes ) | back 1 1. chromosomes are condenced 2. nuclear envelope is dissolved 3. mitotic spindle forms |
front 2 what is the mitotic spindle made of? | back 2 microtubules |
front 3 Metaphase ( 92 chromosomes ) | back 3 spindle fibers attach to kinetochores pulling sister chromatids along the middle of the cell chechoint- ensured metaphase is successful, |
front 4 Anaphase ( 92 chromosomes ) | back 4 spindle fibers contract separating sister chromatids |
front 5 Interphase | back 5 where the cell does most of its work ( cell growth, DNA synthesis, more cell growth and checkpoints ) |
front 6 telophase | back 6 nuclear envelope formed with 42 chromosomes in each nucleus chromosomes DEcondence mitotic spindle breaks down |
front 7 G1 phase of interphase | back 7 growth , gene expression, 46 chromosomes, checkpoint |
front 8 S phase of interphase | back 8 synthesis of DNA, and DNA replication occurs in G2. after S phase there's 92 chromosomes |
front 9 G2 phase | back 9 more growth, more gene expression, checkpoint ensuring DNA replication is successful and makes sure mitosis materials are available |
front 10 why are some parts of the cell cycle longer than others? | back 10 because some are just more complex. like interphase where most of the cells work is being done like cell growth DNA synthase more cell growth and checkpoints. mitosis is just a division of the cell |
front 11 Cytokinesis | back 11 cell divides ,(animal) actin squeezes the cell apart, ending up with 2 seperate cells each with 46 chromosomes |
front 12 plant | back 12 cell wall cant be squeezed apart, plant forms cell plate btw 2 nuclei eventually forming a new cell wall. and then the whole cell cycle starts over |
front 13 prokaryotic cell division | back 13 prokaryotes divide by binary fission |
front 14 binary fission | back 14 1, cell grows 2, DNA replication, 3. cell grows more 4, cell splits in half all happens VERY FAST, as fast as 20mins |
front 15 meiosis | back 15 the reproductive method for germ cells |
front 16 gametes | back 16 sperm, egg |
front 17 goal of meiosis | back 17 diversity |
front 18 goal of mitosis | back 18 identical cells |
front 19 why does meiosis shuffle genes | back 19 to imrove species survival |
