Dna replication Lecture Dna replication Lecture Presentation Transcript

  • DNA Replication
  • DNA Replication: SEMICONSERVATIVE MODELFIG 16.10
  • Semi-conservativeThis processis fueledby…nucleosidetriphosphates
  • DNA is made from5’ to 3’ and it isread from 3’-5’.The 3’ end is theend whichelongates (grows)
  • Leading & Laggingstrands•made 5’-3’Okazaki fragments(are of the laggingstrand)ENZYMES:•Helicase (not shown)•DNA Polymerase•ligase
  • Enzymes•Helicase•Single strand bindingproteins•Primase(RNA Primer)•DNA Polymerase•Ligase•Nuclease and DNAPolymerase(both are repairenzymes)
  • Repairing mistakes
  • Telomeres•Unfilled gap leftat the ends of theDNA strands dueto the use of RNAprimers•Eventualshortening of DNAover time•Dolly, cancer,telomerase
