and these ideas were based on the structure of the DNA molecule. In particular, the duo hypothesized that replication occurs in a "semiconservative" fashion. According to thesemiconservative replicationmodel, which is illustrated in Figure 1, the two original DNA strands (i.e., the twocomplementar...
2.4Spin labeled DNA ‐ structure, dynamics and DNA sequence analysis The major challenge in probingDNAstructure and conformation was introducing the probe at sensitive sites (ie.,purineor pyrimidine bases) which sense local structure, global motion, DNA wobbling, etc. A selected sample of a range...

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 human pluripotent stem cells from 349 individuals. We sho...

1). This structure, known as the open ternary complex, positions Y714 above the center of the dsDNA duplex and relies on a stacking interaction with Y719 to prevent the next 5’ unpaired based in the template from entering the active site. As expected, the phosphate tail of the incoming ...
Transcription-replication conflicts (TRCs), especially Head-On TRCs (HO-TRCs) can introduce R-loops and DNA damage, however, the underlying mechanisms are still largely unclear. We previously identified a chloroplast-localized RNase H1 protein AtRNH1C that can remove R-loops and relax HO-TRCs for...
