Answer: 3' to 5' (template read), synthesizing mRNA 5' to 3'.
- A 5' to 3', the same direction as mRNA synthesis
- B 3' to 5' (template read), synthesizing mRNA 5' to 3'
- C In one fixed direction that never varies across species
- D Bidirectionally, reading both strands simultaneously
Correct answer: B. 3' to 5' (template read), synthesizing mRNA 5' to 3'
Explanation: RNA polymerase reads DNA template 3' to 5' and synthesizes RNA in 5' to 3' direction (complementary to template).
