64. The sequence of a coding strand of DNA is written as 5′-ATGCAA-3′. The sequence of the matching template strand of this DNA segment must be

A. 5'-TACGTT-3'
B. 3'-TACGTT-5'
C. 5'-AUGCAA-3'
D. 3'-AUGCAA-5'

📝 Explanation

The template strand runs anti-parallel and complementary to the coding strand, making the matching sequence 3'-TACGTT-5'.

📖 Additional Information
