IB Biology Topic D1.1.2: Semi-conservative Nature of DNA Replication Notes

DNA Replication Is Semi-Conservative

1. When DNA replicates, the two strands of the double helix separate.
2. Each original strand acts as a template for a new complementary strand.
3. The result is two identical DNA molecules, each with one old strand and one new strand.
4. This preserves genetic information with high fidelity during cell division.
