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. WebThis process fixes mistakes made during DNA replication. During replication in S phase, DNA polymerase can sometimes add an incorrect nucleotide as it duplicates the DNA. DNA polymerase can actually detect this error and remove the incorrect nucleotide. This is called DNA polymerase proofreading how to remove lock in mobile

WebIn case, errors occur during discontinuous replication on the lagging strand, additional mechanisms are involved in repairing these errors. One of these mechanisms is the action of DNA ligase, which joins the fragments of the lagging strand together. Another mechanism is the excision repair system, which removes any damaged or incorrect bases ... WebCell cycle checkpoints. A checkpoint is a stage in the eukaryotic cell cycle at which the cell examines internal and external cues and "decides" whether or not to move forward with division.
