WebJul 30, 2024 · A checkpoint is one of several points in the eukaryotic cell cycle at which the progression of a cell to the next stage in the cycle can be halted until conditions are favorable. These checkpoints occur near the end of G 1, at the G 2 /M transition, and during metaphase (Figure 2). Figure 2. The cell cycle is controlled at three checkpoints.

WebOct 7, 2024 · DNA, found within the nucleus, must be replicated in order to ensure that each new cell receives the correct number of chromosomes. The process of DNA duplication is called DNA replication . Replication … WebThe two stranded molecule passes through the DNA polymerase molecule after synthesis is complete. If the wrong base is inserted then the bond is unstable. Because the double strand is passing through the DNA polymerase the missing base can be detected and replaced. The replacement is done by a different part of the enzyme.
