Fig. 2: Emergence of 2CLCs occurs together with or after DNA replication. a, Strategy to evaluate 2CLC emergence during the S-phase. b, After synchronization of ESCs at G1/S by double thymidine block, existing 2CLCs were removed. The remaining cells were released from the block and cultur...
DNA replication is another critical step of the cell cycle and the fidelity of replication is maintained by checkpoints that guarantee the quality control of DNA integrity, as well as the faithful transmission of the epigenetic marks (Budhavarapu et al., 2013; Probst et al., 2009). Both DNA...
Eukaryotic DNA replication refers to the process by which eukaryotic cells duplicate their DNA, involving the binding of the origin recognition complex (ORC) to replication origins, the formation of pre-replicative complexes (pre-RCs), and the initiation of DNA replication by helicase activity. This...
To ensure that DNA is replicated precisely once per cell cycle, eukaryotic DNA replication initiation involves two steps, with each being restricted to different cell cycle phases1. In the first step (origin licensing), replicative helicase precursors are loaded at origins of replication2; in the ...
the DNA synthesis on the backward extended lagging strand can only be carried out against the extension direction, one by one, and then connected. Such small fragments are called Okazaki fragments. The structure of the replication fork replication bubble leading chain followed by the chain is shown...
RNA is synthesized in the 5' -> 3' direction (as seen from the growing RNA transcript). There are someproofreading mechanismsfor transcription, but not as many as for DNA replication. Sometimes coding errors occur. RNA 以 5' -...

DNA replication follows a strict spatiotemporal program that intersects with chromatin structure but has a poorly understood genetic basis. To systematically identify genetic regulators of replication timing, we exploited inter-individual variation in hu
DNAis directional in both strands, signified by a 5' and 3' end. This notation signifies which side group is attached the DNA backbone. The5' endhas a phosphate (P) group attached, while the3' endhas a hydroxyl (OH) group attached. This directionality is important for replication as it...
