WebJan 16, 2024 · Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. WebPyrimidine dimers are another example that cause errors is replication.
