| Question | Answer |
| What two main phases make up the cell cycle? | Interphase M phase |
| What is interphase? | A period of cell growth and DNA replication. |
| What is the M phase? | A period of cell division (involves mitosis and cytokinesis) |
| What regulates the cell cycle? | Checkpoints |
| Complete the sentences: During ______________ the cell caries out normal functions and prepares to divide. The cell's DNA is _________ and __________, and the organelles are also replicated, | During INTERPHASE the cell caries out normal functions and prepares to divide. The cell's DNA is UNRAVELLED and REPLICATED, and the organelles are also replicated, |
| TRUE OR FALSE: The ATP content of the cell during interphase is increased | TRUE |
| What are the uses of mitosis? | Growth Repair Asexual reproduction |
| What are the 4 stages of mitosis? | Prophase Metaphase Anaphase Telophase |
| What happens in prophase? |
Chromosomes condense
Centrioles move to poles of cell
Nuclear envelope breaks down

| What happens in metaphase? |
Chromosomes line up at the spindle equator
Spindle fibres attach to the centromeres

| What happens in anaphase? |
Centromeres divide, separating each pair of sister chromatids
Spindles contract, pulling chromatids to opposite ends of the cell

| What happens in telophase? |
Chromatids uncoil (now called chromosomes again)
Nuclear envelope forms

Cytoplasm divides
There are now 2 identical daughter cells
Begins in anaphase, ends in telophase
Separate process to mitosis
