  1. Polymerase Chain Reactions:Denaturation, annealing & elongation • 95oC • 50-65oC • 72oC • Polymerase is thermophilic can withstand high temperature

  2. Exponential growth • Generally take through 20-30 cycles • 2(doubling with every cycle)20-30(cycles) • 220 = 106 copies • 230 =109 copies

  3. Cycle Sequencing:Denaturation, annealing & elongation • 95oC • 50-65oC • 72oC • Polymerase is thermophilic can withstand high temperature

  4. Exponential growth No exponential growth thus need fluoro labels to see
