AQA A LEVEL BIOLOGY EXAM SCRIPT
TESTED QUESTIONS AND SOLUTIONS 100
PERCENT CORRECT
◉ Prophase. Answer: The chromosomes thicken and condense,
becoming visible. The nuclear envelope breaks down
◉ Metaphase. Answer: The chromosomes align in the centre of the
cell. Spindle fibres begin to attach to each sister chromatid
◉ Anaphase. Answer: The sister chromatids are pulled apart to
opposite poles of the cell. The centromeres divide in two and move to
opposite poles of the cell, pulled by microtubules
◉ Telophase. Answer: The start of the cell division where the spindle
fibres disintergrate and the nucleolus reforms
◉ Cytokinesis. Answer: The process by which the cell splits into two
at the end of mitosis, forming a new nuclear envelope and plasma
membrane
◉ Chromatid. Answer: Half a chromosome
◉ Homologous Chromosomes. Answer: Identical chromosomes
