DNA Replication

HideShow resource information


  • Chromasome must make copies of themselves for cell division.
  • The copying of DNA is called replication and takes place during interphase.
  • During replication, the hydrogen bonds holding the complimentary base pairs together break and the two DNA strands separate.
  • As the template DNA unwinds/separates, DNA polymerase catalyses the addition of free complimentary nucleotides to free bases.
  • This results in two DNA molecules, each made up of one new chain and one chain conserved from
