DNA polymerase synthesis new DNA strand complementary to the template DNA strand.
RAN polymerase synthesize RNA complementary to the template DNA strand
Helicase enzyme separates the two strands of DNA during replication.
RNA primase produces RNA primer, before DNA replication.
DNA ligase ligates the fragments of DNA.
so the answer is RNA polymerase: makes a molecule of RNA from an RNA template

Which of the following statements about DNA replication is FALSE? Primase synthesizes the primers. DNA polymerase is required to add new nucleotides to the growing ends of the DNA strands. DNA ligase joins the small DNA fragments of the lagging strand. Only one strand of the parent DNA serves as a template for a newly synthesized complementary strand.
