Step-by-Step Solution

According to the textbook, the DNA-dependent RNA polymerase catalyses polymerisation in the 5' → 3' direction, reading the template strand which has 3' → 5' polarity . The transcription follows the rule of complementarity, where Adenine pairs with Uracil (in RNA) instead of Thymine, and Cytosine pairs with Guanine .
