3 ways of DNA replication

• The Conservative method:

  • Original, parental DNA would remain intact
  • A new DNA molecule would be made from scratch

  
• The Semi-conservative method:

  • DNA doubles
  • Each strand acts as a template, to which a new DNA strand can be synthesized
  • Each double-stranded DNA strand has one original DNA strand & one newly synthesised strand

  
• The Dispersive method:

  • The original, parental DNA molecule breaks into fragments
  • These fragments are distributed across the two molecules with the newly, synthesised strands
