Name the direction DNA polymerase adds nucleotides and the role of RNA primase.

• A. It adds nucleotides in the 3' to 5' direction; RNA primase creates RNA primers to start synthesis.
• B. It adds nucleotides in the 5' to 3' direction; RNA primase creates RNA primers to end synthesis.
• C. It adds nucleotides in the 3' to 5' direction; RNA primase unwinds DNA.
• D. It adds nucleotides in the 5' to 3' direction; RNA primase creates RNA primers to start synthesis.

Answer: (D)
