A DNA template strand reads 3′-TAC GGA-5′. Which mRNA sequence is produced?
A.5′-AUG CCU-3′
B.5′-UAC GGA-3′
C.3′-AUG CCU-5′
D.5′-TAC GGA-3′
Explanation
Core Concept
The RNA transcript is complementary and antiparallel to the DNA template, with uracil replacing thymine in RNA. Therefore 3′-TAC GGA-5′ produces 5′-AUG CCU-3′.
Correct Answer
A5′-AUG CCU-3′
