Solution:

The DNA-dependent RNA polymerase catalyses the polymerisation in only one direction that is $5^{\prime} \rightarrow 3^{\prime}$ DNA. RNA polymerase moves from the $3^{\prime}$ end of the template strand, creating an RNA strand that grows in $a 5^{\prime} \rightarrow 3^{\prime}$ direction.
