In which direction does the DNA-dependent RNA polymerase catalyse the polymerisation ?
Answer & explanation
Correct answer: option 2
The two strands have opposite
polarity and the DNA-dependent RNA polymerase also catalyse the
polymerisation in only one direction, that is, 5'→3', the strand that has
the polarity 3'→5' acts as a template, and is also referred to as template
strand.
