| Question | Answer |
| Do cells divide continuously or not? | They do not divide continuously |
| What happens during interphase of the cell cycle (hint- not mitosis). | first growth (proteins are synthesised and produced), synthesis (DNA is replicated) and second growth (organelles grow and divide). |
| What are the three phases of the cell cycle | interphase nuclear division cell division |
| Describe nuclear division | when the nucleus either divides into two (mitosis) or four (meiosis) |
| describe cell division | follows nuclear division in that the whole cell either divides into two (mitosis) or four (meiosis) |
| What can you say about the length of each cell cycle? | varies among different organisms, typically a mammalian cell takes around 24 hours to divide, 90% of this time being interphase |
| What is cancer | A group of cells that divide rapidly and uncontrollably as a result of damage to the genes that regulate mitosis and the cell cycle. |
| What is involved in the treatment of cancer? | Blocking of cell division in order to stop the growth of cells. |
| How does chemotherapy work? | prevents DNA from replicating, it inhibits the metaphase stage of the cell cycle by interfering with spindle formation. |
