Question
- A. It links cellular function directly to Structure of DNA and RNA and explains use base-frequency information to infer complementary dna base frequencies using precise A-Level Biology terminology.
- B. It gives a general definition of structure of dna and rna without applying it to cellular function.
- C. It describes an unrelated biological molecule and leaves the named evidence out of the answer.
- D. It reverses the relationship in the objective and treats the consequence as the cause.
Answer
Correct answer: It links cellular function directly to Structure of DNA and RNA and explains use base-frequency information to infer complementary dna base frequencies using precise A-Level Biology terminology.
Explanation
It links cellular function directly to Structure of DNA and RNA and explains use base-frequency information to infer complementary dna base frequencies using precise A-Level Biology terminology. This is historically generated as an A-Level Biology explanation but remains anchored to the learning objective: Use base-frequency information to infer complementary DNA base frequencies. The distractors are incorrect because they either stay generic, switch to an unrelated molecule, or reverse cause and effect. In an exam answer, the biological claim must be connected to evidence from cellular function, not just repeated as a definition.
Common mistake
