Answer Verified 240.9k + views Hint: Replicating fork is the structure of the DNA double helix after the unzipping by ligase enzyme. This leads to two strands called leading and lagging strands. Complete answer: DNA replication is the process of duplication of DNA during cell … WebAnswer: 1.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. 28. phil saudi family videos
