Answer

Answer:

B. 5' A G G U C U A G 3'

Explanation:

Step1: Identify the template strand for transcription

Transcription uses the non-coding (template) strand, which runs 3' to 5'. The coding strand is complementary and identical to mRNA (with U replacing T).

Step2: Match base pairs with RNA rules

DNA bases pair with RNA as: A→U, T→A, G→C, C→G. The coding strand sequence (5' to 3') is equivalent to mRNA, replacing T with U.

Step3: Determine mRNA sequence from coding strand

Coding strand sequence (5' to 3'): A G G T C T A G. Replace T with U: A G G U C U A G, resulting in 5' A G G U C U A G 3'.
