Examiners report
A teacher complained in the G2s that a nucleolus is not in the syllabus, therefore an inappropriate distracter. It would be possible to only use terms present in the syllabus, but this is very limiting and sometimes it is not sensible to do so. Very few candidates went for that option. This turned out to be an easy question and a good discriminator.
