  • DNA Replication
    • Enzyme helicase breaks the hydrogen bonds to unzip the DNA double helix
      • New nucleotides with the appropriate complementary bases line up opposite the bases of the exposed strands
        • Hydrogen bonds then form between these bonds, holding them in place
          • The sugar and phosphate groups of adjacent nucleotides of the new strand condense together
            • This reaction is catalysed by enzyme DNA POLYMERASE
            • Each pair of strands wind up into a double helix
              • One strand of each new double helix came from the original chromosome and one is a newly synthesised strand, this is known as SEMI-CONSERVATIVE REPLICATION
