PART C: Mitosis
PART C for study guide.
| Question | Answer |
|---|---|
| What is prophase? | centrioles move opposite poles, nuclear envelope disappear, chromosomes coil into visible structure. |
| What is metaphase? | spindle fibres attach on the chromosomes, and line them up in the middle. |
| what is anaphase? | spindle fibre retract and pull 1/2 of the chromosomes towards each centriole. |
| what is telophase? | spindle fibres are pack in the centrioles, nuclear envelopes star to form back around both set of chromosomes. |
| what is mitosis? | the life of a cell, the cell is either growing and developing or diving into 2 daughter cells. |
| what are cell check points? | there are 3 main checkpoints on the cell cycle where protein determine whether the cell should divide or not. |
| what is cytokinesis? | cell membranes priones off in the middle and separate into 2 daughter cells. |
| What is apoptosis? | cells dire when its too old to function. |
| what are cancer cells? | can undergo mitosis an unlimited numbers of times. |
| what is tumor? | cells that clump together due to uncontrollable urge to divide. |
| What is growth phase? | 1st growth phase, cell is growing and developing its organelle. |
| What is synthesis phase? | The chromosomes replicate in the nucleus. 2x chromosomes |
