Select the correct option:

A Direction of RNA synthesis: 5´—3´; direction of reading of the template DNA strand: 3´—5´

B Direction of RNA synthesis: 3´—5´; direction of reading of the template DNA strand: 5´—3´

C Direction of RNA synthesis: 5´—3´; direction of reading of the template DNA strand: 5´—3´

D Direction of RNA synthesis: 3´—5´; direction of reading of the template DNA strand: 3´—5´

Detailed Solution

RNA polymerase adds nucleotides only in the 5´→3´ direction, so it reads the template DNA strand in the 3´→5´ direction.
