A1.2.7—Differences between DNA and RNA Topic Practice
A1.2.7—Differences between DNA and RNA Topic Practice
Practise distinguishing DNA and RNA using strand number, sugars and bases across diagrams, codon choices and structured comparisons.
How this is tested
- compare DNA and RNA by strand number, sugar type and thymine or uracil content
- identify RNA-only sequences by the presence of uracil in codon-style questions
- determine whether a diagram shows DNA or RNA using sugar, base and strand evidence
