Which of the Following is NOT Correct Regarding DNA and RNA

Question

Which of the following is NOT correct regarding DNA and RNA synthesis?
A) The overall direction of chain growth is from the 5ʹ to 3ʹ end.
B) Both processes require an RNA primer to begin.
C) The template strand is antiparallel to the newly synthesized strand.
D) DNA is the template for both DNA and RNA synthesis.

Accepted Answer

While RNA synthesis requires an RNA primer, DNA synthesis does not require an RNA primer to begin. DNA synthesis is initiated by a short RNA primer synthesized by the enzyme primase, but RNA synthesis begins with the binding of RNA polymerase to a promoter region on the DNA template strand without the need for a primer.
