Web31 de mar. de 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. WebReplication forks are formed at each replication origin as the DNA unwinds. The opening of the double helix causes over-winding, or supercoiling, in the DNA ahead of the replication fork. These are resolved with the action of topoisomerases. Primers are formed by the enzyme primase, and using the primer, DNA pol can start synthesis.

Web23 de jul. de 2024 · Once the DNA has been replicated in the synthesis phase, the cell moves on to another phase known as G 2 or Gap 2. During this stage, the cell also duplicates organelles and increases the amount of cytoplasm. This phase goes on until the cell starts dividing through mitosis, starting the whole process again.
