MITOSIS QUIZ - AQA BIOLOGY A LEVEL/AS

What happens in INTERPHASE?
Cell still carries out normal functions, DNA replication, organelles replicate.
1 of 6
What happens in PROPHASE?
Chromosomes get shorter and fatter, tiny bundles of protein called centrioles start moving to opposite poles, nuclear membrane breaks down so chromosomes lie free in the cytoplasm
2 of 6
What happens in METAPHASE?
Spindle fibres attach to the centromeres and the chromosomes line up along the equator of the cell.
3 of 6
What happens in ANAPHASE?
The chromatids are pulled apart, centromere first towards opposite pole by the spindle fibres.
4 of 6
What happens in TELOPHASE?
Chromatids reach their respective poles and become long and thin. A nuclear membrane/nucleolus forms. The cytoplasm divides (CYTOKINESIS) to give two new genetically identical daughter cells.
5 of 6
What is CYTOKINESIS?
Cytoplasm divides to give two new cells
