Nanoconfined Circular DNA [PDF]
Biophysical Journal, 2014 Nanofluidic channels have become a versatile tool to manipulate single DNA molecules. They allow investigation of confined single DNA molecules from a fundamental polymer physics perspective as wel ...

Differences in sequences between HBV-relaxed circular DNA and covalently closed circular DNA
Emerging Microbes and Infections, 2017 The hepatitis B virus (HBV) genome exists in two forms: circular covalently closed DNA (cccDNA) and relaxed circular DNA (RCDNA). Here, we investigated the presence of differences in the sequences of both forms in paired samples of serum and liver tissue.

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

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 ...

Analysis of a circular code model [PDF]
, 2001 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].

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

Condensation of circular DNA [PDF]
The Journal of Chemical Physics, 2013 A simple model of a circularly closed double-stranded DNA in a poor solvent is considered as an example of a semi-flexible polymer with self-attraction. To find the ground states, the conformational energy is computed as a sum of the bending and torsional elastic components and the effective self-attraction energy.

Nucleic acids and protein synthesis in cancer cell mitochondria. I. Nucleic acids in rat hepatoma mitochondria [PDF]
, 1967 The contents of nucleic acids in rat liver and hepatoma mitochondria and the physico-chemical properties on DNA's isolated from these mitochondria were comparatively investigated. The results are briefly summarized as follows. 1.
