Name:____________________________________________ Date:_________ DNA Replication Primase Ligase 3' 5' Okazaki fragment Lagging strand Polymerase Leading strand Single-Strand binding proteins Helicase Identify the structure Helicase 1. _____________________________ Enzyme that unwinds DNA Okazaki fragments 2. _____________________________ Fragments of copied DNA created on the lagging strand leading strand 3. _____________________________ The strand that is copied in a continuous way, from the 3’ to 5’ direction ligase 4. _____________________________ Binds Okazaki fragments polymerase 5. _____________________________ Builds a new DNA strand by adding complementary bases helicase 6. _____________________________ Stabilizes the DNA molecule during replication leading 7. _____________________________ Strand that is copied discontinuously because it is traveling away from helicase Primase 8. _____________________________ Initiates the synthesis DNA by creating a short RNA segment at replication fork 9. Place the events in the correct order: 2 ____ DNA polymerase adds nucleotides in the 5’ to 3’ direction 4 ____ Replication fork is formed 3 ____ DNA polymerase attaches to the primer 1 Okazaki fragments are bound together by ligase ____ 5 DNA helicase unwinds DNA ____ one strand from each parent is conserved and remains intact after DNA 10. Why is replication called “semi-conservative?” ___________________________________________________ replication.   
