26. The template strand of a structural gene possesses the sequence 3′-TACGGC-5′. The matching codon sequence present on the mRNA transcript will be

A. 5'-ATGCCG-3'
B. 5'-AUGCCG-3'
✓
C. 3'-AUGCCG-5'
D. 5'-UACDDC-3'

📝 Explanation

Transcription generates an RNA transcript that is complementary and anti-parallel to the DNA template strand, swapping thymine for uracil.
