Webb31 mars 2024 · When DNA is replicated, the leading strand is built as a continuous piece (due to the polymerase only being able to add itself to the 3’ end), while the lagging strand is built as a discontinuous piece. The lagging strand is built discontinuously because the DNA double helix must unwind a bit before the addition of another primer. Webb16 jan. 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.
