DNA template sequence of CTGATAGC is transcribed over mRNA as

1. GUCUTUCG
2. GACUAUCG
3. GAUTAUUG
4. UACUACU

Correct answer: GACUAUCG

Solution

During transcription, mRNA is synthesized as the complementary strand to the DNA template. Applying RNA pairing rules to CTGATAGC gives GACUAUCG, which matches option B.
