a. Daughter strands are formed using complementary base pairing. b. DNA unwinds. c. The DNA of the daughter strands winds together with its parent strand. 2. Why is DNA replication called "semi-conservative"? 3. What enzyme unwinds or unzips the parent strand? 4. What enzyme connects the new bases to the old bases in the DNA template? 5. ___ DNA replication results in two DNA molecules, a. each with two new strands b. one with two new strands and one with 2 original strands c. each with two original strands d. each with one new strand and one original strand 6. ___ DNA replication is said to be semiconservative because: a. both RNA and DNA synthesis are involved in the process. b. part of the telomere is lost during each round of replication. c. a new double helix contains one old and one new strand. d. each new strand is complementary, not identical, to its template.

During replication of a DNA molecule, the daughter strands are not produced in exactly the same manner. One strand, the leading strand, is made toward the replication fork, while the lagging strand is made in fragments in the opposite direction. This difference in the synthesis of the two strands is the result of which of the following? a. DNA polymerase is not fast enough to make two leading strands of DNA. b. The two template strands are antiparallel, and DNA polymerase makes DNA only in the $5^{\prime}$ to $3^{\prime}$ direction. c. The lagging strand is the result of DNA breakage due to UV light. d. The cell does not contain enough nucleotides to make two complete strands.
