mitosis and cell
| Question | Answer |
|---|---|
| mitosis is the process in which cells | mulitpy and divide creating new cells |
| in mitosis identical chromosomes | aligned and pulled apart by fibers just before cytoplasm |
| what is mitosis | to create wo identical daughter cells that are gentically identical to the parent cell |
| what kind of cells would perform mitosis | somatic cells all body cells except ( gamatic cells |
| what hold the chromsomes together | centromeres |
| which phase is not part of mitosis | interphase |
| what does interphase involve | synthsis of new orgenelles (G1- S- G2 - |
| IN INTERPHASE chromes appear as | threadlike structure |
| how many divistions in mitosis | 1 |
| hw many daughter cells are in mitosis | 2 |
| is mitosis gentically identical | yes |
| howy many chromosomes | same as parents |
| in prophase the nucleaus will disappear | n |
| Bacterial cells divide by: | . binary fission |
| Most eukaryotic organisms have ______________ chromosomes in their cells. | 10-50 |
| Replicate copies of each chromosome are called _____________ and are joined at the ________________ | sister chromatids/centromere |
| During which phase of the cell cycle is DNA synthesized? | s |
| Chromosomes are visible under a light microscope during | mitosis |
| During mitosis, the sister chromatids are separated and pulled to opposite poles during which stage of mitosis? | anaphase |
| Cytokinesis is | the separation of cytoplasm and the formation of two cells. |
| What causes cancer in cells? | . damage to genes |
| . During interphase: | The cell grows cell is forming b. Chromosomes start to duplicate c. The cell prepares for mitosis |
| . Diploid cells have: | 43 chromosomes |
| During prophase, the centrioles: | Move to opposite ends of cell and form 2 separate poles |
| The four stages of mitosis in their correct order are: | Prophase, Metaphase, Anaphase, Telophase |
| The chromosomes are pulled apart by the spindle fibers during which stage: | anaphase |
| . During metaphase | line up in the center |
| In which stage do the nuclear envelopes form around the separate sets of chromosomes: | telephase |
| G1 | replications of chromosomes growth in which the cell creates organelles and begins metablism |
| s | Dna and synthesis f proteins necessay for mitosis chromosomes copied |
| g2 | grows preparing for cell division |
| what type of cells does the cell cycle occur | eukaryotes |
| 2 main phases of the cell cycle | interphase and metotic pase |
| what is occuring during mitosis | replicating it self |
| charmatides made up of | dna |
| how long is human cell in interphase | 22 hours |
| 3 stages of interphase | g1, s, g2 |
| what stage does cells exit | G1 |
| 3 types of cells tht enter into g0 | heart, brain, eyes |
| what happens if g0 cells are damaged | cant be replaced |
| what stage occurs after cytokinesis | g1 |
| what part of the cell in divided in cytokinesis | cytoplasm |
| shortest phase | G2 |
| how long is g2 | 4 to 5 hrs |
| how is cell prepared for mitosis | enzymes |
| after g 2 phase | m phase |
| what part of the cell is diving in mitosis | nucleaus |
| whats another name for mitosis | karykinesis |
| are chromosomes duplicated before or after mitosis | before |
| nucleaus diving during --------------- while cytoplasm is diving during --------- | mitosis, cytokinsis |
| how does cytokinsis occur sin animal cells | cleavage furrow |
| how does cytokinsis form in plants | cell plate |
| what is used to help break down nuclear membrane | enzymes |
| what is broken down during prophase | nucleaus and nuclear membrane |
