Presentation Transcript

  1. DNA Replication

  2. Process by which the DNA is copied to make an exact copy of the original. • Required step before cell division. • Each strand of the DNA molecule has all the information needed to build the other half. (Chargaff’s Rules/Base Pairing). DNA Replication

  3. DNA Polymerase • Enzyme that joins individual nucleotides to produce a DNA molecule. Nucleotide • Helicase • Enzyme that unzips the DNA by breaking the hydrogen bonds between the base pairs. Nucleotide

  4. Helicase unzips the two strands DNA Polymerase adds nucleotides
