DNA replication

• Cell division


  Parent cell (2 copies of DNA)-> 2 daughter cells (enables each daughter cell to receive one copy)
• Step 1

  Unwinds double helix: cuts base pairs that connect sugar-phosphate backbones to expose nitrogen bases
• Step 2

  Bonds new nucleotides to exposed spaces: added based on complementary base pairing, found in nucleus
• Step 3

  Chain formation: re-binding backbones to form identical nucleotide sequences
