Hepatitis B virus (HBV) covalently closed circular DNA (cccDNA) plays a pivotal role in the establishment and persistence of HBV infection. Understanding the turnover time of preexisting cccDNA pools would be helpful in designing strategies to clear HBV ...

Statistical analysis on detecting recombination sites in DNA-beta satellites associated with the old world geminiviruses [PDF]
Although an exchange of genetic information by recombination plays an important role in the evolution of viruses, it is not clear how it generates diversity.

Using circular DNA to measure the degree of unwinding of the double helix caused by ligand binding was one of the first applications of the specific properties of circular DNA. The approach is conceptually simple. Consider a nicked circular DNA of N base pairs that is bound to molecules of a ligand so that the ratio of bound ligands to base pairs is ...

Circular DNAs derived from single-stranded RNA viruses play important roles in counteracting viral infection. However, whether double-stranded RNA viruses generate functional circular DNAs is still unknown. Using circDNA sequencing, divergent PCR, DNA in

Background: The aim of this study was to develop a nucleotide geometrical model of the circular mitochondrial DNA (mt-DNA) structure using Geant4-DNA toolkit to predict the radiation-induced damages such as single-strand breaks (SSB), double-strand ...

Small Circular DNA Molecules as Triangular Scaffolds for the Growth of 3D Single Crystals
DNA is a very useful molecule for the programmed self-assembly of 3D (three dimension) nanoscale structures. The organised 3D DNA assemblies and crystals enable scientists to conduct studies for many applications such as enzymatic catalysis, biological ...

Construction of DNA hemicatenanes from two small circular DNA molecules. [PDF]
DNA hemicatenanes, one of the simplest possible junctions between two double stranded DNA molecules, have frequently been mentioned in the literature for their possible function in DNA replication, recombination, repair, and organization in chromosomes ...

Circular DNA elements of chromosomal origin are common in healthy human somatic tissue
The human genome is generally organized into stable chromosomes, and only tumor cells are known to accumulate kilobase (kb)-sized extrachromosomal circular DNA elements (eccDNAs).

Propagation of genetic information is a fundamental prerequisite for living cells. We recently developed the replication cycle reaction (RCR), an in vitro reaction for circular DNA propagation, by reconstitution of the replication cycle of the ...

Analysis of a circular code model [PDF]
A circular code has been identified in the protein (coding) genes of both eukaryotes and prokaryotes by using a statistical method called Trinucleotide Frequency method (TF method) [Arquès & Michel, (1996) J.Theor. Biol. 182, 45-58].
