DNA replication takes place during the S phase of interphase in a cell's life cycle. In this phase, a new copy of DNA is synthesized. It is proofread before entering into mitosis or cell division. Answer and Explanation: Learn more about this topic: ...
In eukaryotes, the vast bulk of DNA synthesis takes place during the S phase of the cell cycle, and the entire genome must be unravelled and replicated in order to produce two daughter copies of the organism. It takes three essential phases for DNA replication to occur: first, the opening...

Initiation of DNA replication in eukaryotes begins with the binding of theorigin recognition complex(ORC) toorigins of replicationduring the G1phase of the cell cycle. The ORC complex then serves as a platform for forming much more complicated pre-replicative complexes (pre-RCs). Formation of pre...

Moreover, problems encountered during DNA replication (replication stress) often result in under-replicated DNA that needs to be resolved during mitosis. Cells have developed a number of means to respond to these challenges, such as replication-coupled DNA repair pathways and S-phase checkpoint ...
How do DNA mutations occur, and in what phase of the replication cycle are they most likely to occur?DNA MutationDNA mutations are when the identity of a nucleotide changes during the lifetime of an individual or during the creation of new DNA in advance o...

WEE1 stabilizes replication forks during the S-phase and activates the G2/M checkpoint, providing sufficient time for the DDR machinery to restore the error. Therefore, WEE1 inhibition drives cells into mitosis without proper DNA damage repair and increases replication stress, resulting in mitotic ...
The intra-S-phase checkpoint was among the first reported cell cycle checkpoints in mammalian cells. It transiently slows down the rate of DNA replication after DNA damage to facilitate repair and thus prevents genomic instability. The ionizing radiation (IR)-induced intra-S-phase checkpoint in ma...
