- A Template: 3 prime-TACGGC-5 prime; mRNA: 5 prime-AUGCCG-3 prime
- B Template: 5 prime-TACGGC-3 prime; mRNA: 5 prime-UACGGC-3 prime
- C Template: 3 prime-ATGCCG-5 prime; mRNA: 5 prime-ATGCCG-3 prime
- D Template: 3 prime-TACGGC-5 prime; mRNA: 3 prime-AUGCCG-5 prime
Correct answer: A. Template: 3 prime-TACGGC-5 prime; mRNA: 5 prime-AUGCCG-3 prime
Explanation: The template strand is complementary and antiparallel to the coding strand (3 prime-TACGGC-5 prime), and mRNA has the same sequence as the coding strand except T is replaced by U, giving 5 prime-AUGCCG-3 prime.
