1. { DNA Replication

2.  When DNA makes an exact copy of itself.  Required step before cell division (making new cells).  DNA is the template / Enzymes do the work.  Follows rules of base pairing (Chargaff’s Rules)  Each body cell gets a complete set of identical DNA DNA Replication

3. Semi-conservative: Each new strand of DNA is ½ old (original) DNA and ½ new DNA.

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

6. Helicase unzips the two strands DNA Polymerase adds nucleotides
