CAIE A Level Biology 9700 · The mitotic cell cycle
A student observes a cell in which the sister chromatids are being pulled apart towards opposite poles of the spindle. Outline the sequence of events that take place during the mitotic cell cycle from the start of prophase to the end of telophase, including the behaviour of chromosomes, nuclear envelope, spindle fibres, and cell surface membrane.
7 marks, so the mark scheme is looking for about 7 separate creditworthy points. Making the same point twice in different words earns it once.
Outline means: Give the main points briefly. Less detail than describe, but every key step has to be there. One short line per step, in order. The marks are for coverage, not depth.
