DNA Replication

• Describe how DNA replication occurs(semi-conservative replication)

  • DNA helicase unwinds DNA by breaking hydrogen bonds
  • both strands act as templates
  • nucleotide line up in complementary pairs
  • DNA polymerase joins nucleotide of new strand in the condensation reaction
  • forms phosphodiester bonds
  • Each new DNA molecules consists of one original strand and one new strand
