- metaphase⇔chromosomes line up along the equator of the cell ✓
- anaphase⇔chromosomes split and chromatids are pulled to each side of the cell ✓
- telophase⇔chromatids decondense and the nuclear membrane reforms ✓
- Which statements about the cell cycle are true?
- two genetically identical daughter cells are produced ✓
- cytokinesis occurs before metaphase
- during interphase the cytoplasm begins to divide
- the two main phases are interphase and mitosis ✓

Lesson Details
Key learning points
- Most cells in multicellular organisms go through different phases that are part of a cell cycle.
- The main phases of the cell cycle are interphase and mitosis.
- During cell interphase, each chromosome is copied, sub-cellular structures are copied.
- The stages of mitosis are prophase, metaphase, anaphase, telophase and cytokinesis.
Common misconception
Pupils may think that daughter cells have different DNA to the parent cell.
Slides repeatedly address the concept that DNA is copied and that daughter cells are genetically identical.
Keywords
Cell cycle - The process by which cells divide; this involves a specific set of phases.
Mitosis - A type of cell division that produces genetically identical cells.
Nucleus - A sub-cellular structure that contains the genetic material (DNA); controls the cell activities.
Chromosomes - Tightly coiled strands of DNA that carry the genetic material.
