Subcellular organization of the bacterial nucleoid and spatiotemporal dynamics of DNA replication and segregation have been studied intensively, but the functional link between these processes remains poorly understood. Here we use quantitative time-lapse ...
DNA in bacterial chromosomes and bacterial plasmids is supercoiled. DNA supercoiling is essential for DNA replication and gene regulation. However, the density of supercoiling in vivo is circa twice smaller than in deproteinized DNA molecules isolated from ...
In both eukaryotic and prokaryotic DNA sequences of 30-100 base-pairs rich in AT base-pairs have been identified at which the double helix preferentially unwinds. Such DNA unwinding elements are commonly associated with origins for DNA replication and tran ...
The invention relates to a method of preparing template constructs for solid-phase nucleic acid amplification and to use of the templates in methods of solid-phase nucleic acid amplification. The method involves carrying out two ligation reactions: (a) a l ...
The discrete regulation of supercoiling, catenation and knotting by DNA topoisomerases is well documented both in vivo and in vitro, but the interplay between them is still poorly understood. Here we studied DNA catenanes of bacterial plasmids arising as a ...
Pif1, an evolutionarily conserved helicase, negatively regulates telomere length by removing telomerase from chromosome ends. Pif1 has also been implicated in DNA replication processes Such as Okazaki fragment maturation and replication fork pausing. We fi ...
The invention relates to methods of generating templates for a nucleic acid sequencing reaction which comprise: providing at least one double-stranded nucleic acid molecule, wherein both strands of the double-stranded nucleic acid molecule are attached to ...
