DNA replication

• The semi-conservative replication of DNA ensures genetic continuity between generations

  of cells meaning that genetic information is passed on from one generation from the next.
• The double helix unwinds and the hydrogen bonds between the complementary

  bases break using DNA helicase thus separating the two strands of DNA.

  
• Both strands are used as

  templates and complementary base

  pairing occurs between the template

  strands and free nucleotides.

  
• Adjacent nucleotides are

  joined by phosphodiester bonds

  formed in condensation reactions

  using DNA polymerase.
