A biologist is observing a sample of actively dividing cells from a root tip. One cell is clearly in anaphase. Outline the key events occurring in this cell at anaphase. Include the behaviour of sister chromatids, the spindle fibres, the nuclear envelope, and the cell surface membrane.

The mitotic cell cycle: outline question
Outline5 marksStandard
How this question is marked
5 marks, so the mark scheme is looking for about 5 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.
