QUIZ 1. What kind of replication occurs in the replication of DNA? a. Conservative b. Semi-conservative c. Dispersive d. A combination of semi-conservative and dispersive Answer: b. Research has proven that DNA replication is semiconservative, which involves splitting of the DNA strand and the formation of a new strand half on the opposite side of both parent strands. 2. What enzyme is most responsible for DNA replication? a. DNA polymerase b. Helicase c. DNA gyrase d. Topoisomerase Answer: a. The main enzyme that is responsible for DNA replication is DNA polymerase, which is responsible for creating the daughter strand on the DNA molecule. 3. What is not a difference between eukaryotic DNA replication and prokaryotic DNA replication? a. The eukaryotes synthesize DNA in the three-prime to five-prime direction as well as the five-prime to three-prime direction. b. The prokaryotes have DNA polymerase while the eukaryotes do not. c. Eukaryotes do not have DNA ligase. d. Eukaryotes have multiple origins of replication and prokaryotes have just one of these.
