MITOSIS
| Question | Answer |
|---|---|
| Mitosis | process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets, in two separate nuclei. |
| Where does Mitosis occur? | occurs only in eukaryotic cells and the process varies in different species |
| The process of mitosis is | fast and highly complex |
| How is the sequence of events divided? | The sequence of events is divided into stages corresponding to the completion of one set of activities and the start of the next. |
| Stages of Mitosis | These stages are interphase, prophase, prometaphase, metaphase, anaphase and telophase. |
| What happens during mitosis to the pairs of chromatids? | During mitosis the pairs of chromatids condense and attach to fibers that pull the sister chromatids to opposite sides of the cell |
| What is the result of Mitosis? | The primary result of mitosis is the transferring of the parent cell's genome into two daughter cells. |
| what happens to the nuclear envelope? | In most eukaryotes, the nuclear envelope which segregates the DNA from the cytoplasm disassembles |
| What is Metaphase? | " Microtubules find and attach to kinetochores in prometaphase. |
| WHat is Anaphase? | When every kinetochore is attached to a cluster of microtubules and the chromosomes have lined up along the metaphase plate, the cell proceeds to anaphase |
| What is Telophase? | Telophase (from the Greek τελος meaning "end") is a reversal of prophase and prometaphase events |
| What is Cytokinesis? | Cytokinesis is often mistakenly thought to be the final part of telophase; however, cytokinesis is a separate process that begins at the same time as telophase. |
| Developement and Growth | The number of cells within an organism increases by mitosis |
| Mitosis is specifically what? | is specifically the process of division of the chromosomes |
| What is tissue culture? | One interesting offshoot of the study of mitosis is tissue culture. In tissue culture, the cells to be studied are removed from the organism’s body and grown on a sterile, artificial medium. |
| Daughter Cells | The daughter cells are identical to one another and to the original parent cell. |
| cell cycle | is the series of events that take place in a cell leading to its division and duplication (replication). |
| in cells without a nucleus.... | the cell cycle occurs via a process termed binary fission. |
| How is the cell division process vital? | The cell-division cycle is a vital process by which a single-celled fertilized egg develops into a mature organism, as well as the process by which hair, skin, blood cells, and some internal organs are renewed. |
| What are the stages of the Cell cycle? | interphase, mitosis, cytokinesis |
| Why must cell energy be balanced? | to maintain function and balance |
| When a cell must divide what does it do first? | it must replicate DNA |
| What happends during the prophase stage of mitosis? | replicated chromosomes condense. |
| What happens at metaphase? | nuclear envelope breaks down |
