When DNA is replicated, new nucleotides are added onto which end of the growing strand? A. New nucleotides are added onto both ends. B. New nucleotides are added onto only the 5' end (where a phosphate group, PO4-, is exposed). C. New nucleotides are added onto only the 3' end (where a hydroxyl, -OH, is exposed). D. New nucleotides can be added onto either end, depending on the enzymes available. Answer Key: C Question 2 of 8 0.5/ 0.5 Points I f you add template DNA, DNA polymerase, and triphosphate nucleotides of DNA  to a test tube, nothing happens. It turns out that DNA polymerase is unable to  put the first nucleotides in place against a single-strand of template DNA. What  enzyme must be present to add nucleotides against the template, to begin  synthesis of DNA? A. DNA ligase B. Primase C. RNA polymerase D. Helicase Answer Key: B Question 3 of 8 0.5/ 0.5 Points Within a replication fork, one strand of new DNA is elongated toward the  replication fork. This strand is termed
