The mitotic cell cycle: outline question

Outline5 marksStandard

A student is observing a stained slide of an animal cell undergoing mitosis. They identify a cell in anaphase.

Outline the major events that occur during anaphase, including:

the behaviour of sister chromatids
the role of spindle fibres
changes to the nuclear envelope and cell surface membrane

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.
