Mitosis
Mitosis Test
| Question | Answer |
|---|---|
| What is Mitosis? | Mitosis is the process of which the human body produces new cells for growth and repair. |
| What is S-Phase important for? | S-Phase is important for mitosis to occur. |
| What happens during S-Phase? | A process called DNA REPLICATION happens |
| S-Phase: What does DNA REPLICATION allow? | This allows the chromosones to duplicate; attached at the centromere. |
| What happens during Early Prophase? | The chromosones begin to coil; The nuclear membrane begins to break down, which will eventually be recycled. |
| What is a spindle fiber? | A spindle fiber is hollow like a 3D football. |
| What does a centriole do during Late Prophase? | Centrioles connect to the spindle fibers on either end. |
| In late prophase, what are the spindle fibers and centriole made from? | Recycled membrane |
| What happens during Late Prophase? | The spindle fibers and centrioles form; The chromosones are fully coiled |
| What happens during Metaphase? | The chromosones attach to the spindle fibers at the centromere on the "metaphase plane" |
| What happens during Anaphase? | The spindle fibers are getting pulled to either end and the duplicated chromosones (chromatios) are pulled to either end; They split at the centromere |
| What happens during Telophase? | The new nuclear membranes are forming around the chromosones at either end, made from recycled spindle fibers and centriole; New cell wall is starting to form in the middle; chromosones are starting to uncoil |
| What happens during Cytokinesis? | Now have 2 daughter cells of which are identical to each other and the original cell (2 pairs) |
| What word represents the order of phases? | SELMATC |
| In what order do the phases go? | S-Phase; Early Prophase; Late Prophase; Anaphase; Metaphase; Telophase; Cytokinesis |
