Unformatted text preview: Semi conservative model is used How do you make exact copies? What does the structure of DNA tell you about how to copy it? DNA Replication Figure 16.13 Begins at many origins Strands must separate and unwind Enzymes involved--Helicase- responsible for unwinding separating backbone-Toposiomerases- works away from orgin and relieve stress caused from unwinding in the center -SSB Proteins- keeps back bons apart, single-strand binding proteins Add primer Primase- builds primer, built antiparallel 5’ 3’ Replication DNA polymerase- makes DNA Fuse Sections DNA ligase- responsible for fusing sections together...
