A)DNA helicase builds RNA primers on the existing DNA strands.

During the S phase of interphase, DNA helicase unwinds the two strands of the DNA double helix, allowing DNA polymerase to synthesize new strands by adding complementary nucleotides. Helicase does not build RNA primers, remove RNA primers, or catalyze the addition of nucleotides.
