Which of the following statements is true regarding DNA replication?. Single choice. A. During leading strand synthesis, DNA polymerase synthesizes short, discontinuous strands of DNA. B. During lagging strand synthesis, ligase joins together multiple Okazaki fragments. C. During leading strand synthesis, a DNA primer helps initiate DNA synthesis. D. During lagging strand synthesis, topoisomerase separates complementary strands of DNA.

Which of the following is true regarding DNA replication? Ligase synthesizes most of the DNA and then joins the Okazaki fragments together. DNA polymerase III reads the template strand and makes new DNA by adding to the 3' end of the growing strand. RNA polymerase makes new DNA from a DNA template. DNA polymerase I reads the template strand and makes new DNA by adding to the 5' end of the growing strand.

$\mathrm{PCR}$ a. uses RNA polymerase. b. takes place in huge bioreactors. c. uses DNA replication in vitro. d. makes many nonidentical copies of DNA. e. All of these are correct.
