DNA is a double-stranded helix. Which strand is involved in transcription?

Question

A. Coding strand (runs in the 3’ - 5’ direction)

B. Template strand (runs in the 5’ - 3’ direction)

C. Template strand (runs in the 3’ - 5’ direction)

D. Leading strand (runs in the 3’ - 5’ direction)

Answer 1

C. Template strand (runs in the 3’ - 5’ direction)

The template strand is anti parallel running in the 3' to 5' direction. The RNA polymerase binds to the promotor and starts transcribing the template strand by moving downstream. The enzyme adds nucleotides to the 3' end of the mRNA transcript.
