Hepatitis B virus cccDNA is formed through distinct repair processes of each strand
Nature Communications, 2021 HBV covalently closed circular DNA (cccDNA) enables and persists in chronic infection, but the molecular mechanism of its formation is unclear. Here, Wei and Ploss elucidate the detailed kinetics and biochemical steps by which the relaxed circular DNA is

Deciphering extrachromosomal circular DNA in Arabidopsis
Computational and Structural Biotechnology Journal, 2021 Extrachromosomal circular DNA (eccDNA) is independent of the chromosome and exists in many eukaryotes. However, the nature and origin of eccDNA in plants remains unclear.

Circular Dichroism of DNA [PDF]
European Journal of Biochemistry, 1970 The circular dichroism of sixteen DNA samples from fourteen species has been determined. Plots of molar ellipticity against base composition show considerable scatter, which is much too great to be accounted for in terms of reproducibility of materials and measurements.

DNA-like Helices as Nanosized Polarizers of Electromagnetic Waves
Frontiers in Nanotechnology, 2022 The possibility of using a conducting double DNA-like helix as the basis of an electromagnetic wave polarizer, which converts an incident linearly polarized wave into a reflected wave with circular polarization, has been shown. A high-frequency resonance

Mitochondrial DNA from hamster tumors induced by adenovirus type 12 [PDF]
, 1970 1. Mitochondria isolated from hamster tumors induced by adenovirus type 12 possessed circular DNA fibers. 2. The mean value of the length of the highest frequency group of the circular DNA molecules was 4.92 ±0.38 μ. 3. Catenated dimer DNA molecules

Proceedings of the National Academy of Sciences, 1998 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 ...

Determination of plasmid copy number in yeast transformants by means of agarose plugs [PDF]
, 1993 The determination of plasmid copy number in Saccharomyces cerevisiaetransformants containing circular or linear plasmids is currently performed with total yeast DNA extracts obtained from cultures grown under selection.

Characterization of the DNA binding activity of structural protein VP1 from chicken anaemia virus
BMC Veterinary Research, 2018 Background Chicken anaemia virus (CAV) is commonly found in poultry. VP1 is the sole structural protein of CAV, which is the major component responsible for capsid assembly. The CAV virion consists of the VP1 protein and a viral genome. However, there is

Circular DNA's from HeLa cell nuclei and mitochondria [PDF]
, 1970 An electron microscopic observation was made on the DNA's extracted from purified HeLa cell nuclei, mitochondria, and the whole cell, and fractionated by ethidium bromide-cesium chloride density gradient method or sucrose density gradient method. Nuclear

Single-stranded circular DNA theranostics
Theranostics, 2022 The past decade has witnessed the blossom of nucleic acid therapeutics and diagnostics (theranostics). Unlike conventional small molecule medicines or protein biologics, nucleic acid theranostics have characteristic features such as the intrinsic ability as "information drugs" to code and execute genetic and theranostic information, ready ...
