Summary Introduction
To answer:
The interpretation of the RNA polymerase function with the DNA polymerase function, apart from the fact that it synthesizes RNA.
Introduction:

What is the difference between the leading strand and the lagging strand in DNA replication?
There are different DNA polymerases involved in elongation of the leading strand and the lagging strand.
The leading strand is synthesized continuously in the 5' → 3' direction, while the lagging strand is synthesized discontinuously in the 5' → 3' direction.
The leading strand requires an RNA primer, whereas the lagging strand does not.
The leading strand is synthesized in the 3' → 5' direction in a discontinuous fashion, while the lagging strand is synthesized in the 5' → 3' direction in a continuous fashion.
Which of the following statements most accurately describes the action of the enzyme RNA polymerase?Select one
1.) RNA polymerase will transcribe only the exons by skipping over the introns within a eukaryotic gene sequence
2.) RNA polymerase will transcribe both DNA strands, moving in the 3' to 5' direction for one strand and 5' to 3' on the other
3.) RNA polymerase will transcribe both DNA strands, but only one RNA molecule will be used during translation
4.)None of the statements accurately describe the function of RNA polymerase
In what ways are DNA polymerase and RNA polymerase similar? How do they differ?

- Which of the followings statements are true about DNA polymerase? 1.) It can only go in one direction, meaning the lagging strand can't be synthesized continuously. 2.) It cannot start a DNA strand from scratch, so another enzyme is needed to create "primers" as a starting point. 3.)
