Name:____________________________________________ Date:_________ DNA Replication - Labeling (with word bank) DNA polymerase 3’ 5’ Single Strand Binding Proteins DNA Ligase Helicase Ligase Okazaki fragment Leading Strand DNA Primase Lagging Strand Primase okazaki Lagging Polymerase Leading Helicase Single strand binding Proteins Identify the structure 1. Helicases Enzyme that unwinds DNA 2. Okazaki fragments Fragments of copied DNA created on the lagging strand 3. leading strand The strand that is copied in a continuous way, from the 3’ to 5’ direction 4. ligase Binds Okazaki fragments 5. Polymerase Builds a new DNA strand by adding complementary bases 6. Helicase Stabilizes the DNA molecule during replication 7.leading Strand that is copied discontinuously because it is traveling away from helicase 8. Primase 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 10. Why is replication called “semi-conservative?” because two copies of the original DNA molecule are produced
