It is conceivable that with the advance of the replication fork, the helix of the remaining DNA will become more and more compact, which will cause greater resistance. The negative super helix leaves room for a certain buffer, which is conducive to DNA replication. On the other hand, DNA he...
The chromosome origin of Escherichia coli 15T- was labeled with radioactive density labels. Premature replication of such labeled DNA was measured after thymine starvation. The selection of template DNA for premature replication was found to be independent of age or polarity of the template. It is...

DNA replication initiates from replication origins firing throughout S phase. Debate remains about whether origins are a fixed set of loci, or a loose agglomeration of potential sites used stochastically in individual cells, and about how consistent thei
12. R-loops thus acting as barriers hinder DNA replication and even induce DNA breaks at common fragile sites13. RNA and DNA polymerases occurring at the same genomic loci could lead to transcription and replication collisions (TRCs) that are normally associated with constant and stabilized R-...
DNA synthesis is a complicated process involving anabolic processes to create the purine and pyrimidine nucleotide triphosphates required for replication, unwinding of the template DNA to provide access to the replication machinery, and the high fidelity process of creating complementary strands. ...

Sequence analysis of yeast DNA segments able to promote autonomous replication suggests that they may be similar in structure to origins of replication recognized by E. coli. This report describes the use of single-stranded circular DNA molecules containing such DNA segments in an in vitro system ...
In a human cell, thousands of replication forks simultaneously coordinate duplication of the entire genome. The rate at which this process occurs might depend on the epigenetic state of the genome and vary between, or even within, cell types. To accurate
