Markscheme

A table format is not required but clear distinctions must be apparent.

The full names of the bases must be given.

Examiners report

This question was well answered by most. Students are cautioned against representing bases with letter symbols such as A,C,T,G and U. The expectation of the mark scheme is that students write out the full names.
