How DNA is copied
In short: The two strands of DNA separate and each one is a template for a new partner strand.
1. DNA is a double helix: two strands wound around each other. 2. Helicase enzymes unwind the helix and separate the two strands. 3. Each separated strand acts as a template for a new partner strand. 4. DNA polymerase adds matching nucleotides: A with T, and C with G. 5. Each new DNA molecule has one old strand and one new strand.
