A1.2.8—Complementary base pairing Topic Practice
Practise using complementary base pairing to deduce bases from DNA diagrams and calculate base percentages in DNA samples.
How this is tested
- deduce missing DNA bases from labelled diagrams using adenine-thymine and cytosine-guanine pairing
- calculate base percentages when one DNA base proportion is given in MCQ or structured data
- link complementary base pairing to replication, transcription and translation when comparing processes
