Phylogeny and DNA-DNA hybridization. [PDF]
Molecular Biology and Evolution, 1986 Resolving the phylogeny of the hominoid primates is a test case for molecular systematic methods because, by most genetic measures, humans, chimpanzees, and gorillas are very closely related. Recently, Sibley and Ahlquist (1984) applied DNADNA hybridization techniques to infer the hominoid phylogenetic tree with humans and chimpanzees closest ...

Potentiometric Detection of DNA Hybridization [PDF]
Journal of the American Chemical Society, 2007 The use of potentiometric microsensors is demonstrated here for the first time to detect DNA hybridization. Cadmium sulfide nanocrystal labels bound on a secondary oligonucleotide are dissolved and detected with cadmium-selective microelectrodes exhibiting DNA detection limits of ca. 2 fmol in a 200 μL sample.

DNA-DNA hybridization study of Bradyrhizobium strains. [PDF]
International Journal of Systematic and Evolutionary Microbiology, 2001 DNA-DNA hybridizations were performed between Bradyrhizobium strains, isolated mainly from Faidherbia albida and Aeschynomene species, as well as Bradyrhizobium reference strains. Results indicated that the genus Bradyrhizobium consists of at least 11 genospecies, I to XI.

Current Opinion in Chemical Biology, 2015 In the past decade, DNA-based hybrid catalysis has merged as a promising novel approach to homogeneous (asymmetric) catalysis. A DNA hybrid catalysts comprises a transition metal complex that is covalently or supramolecularly bound to DNA. The chiral microenvironment and the second coordination sphere interactions provided by the DNA are key to achieve

Software for DNA sequencing by hybridization [PDF]
Bioinformatics, 1997 Sequencing by hybridization (SBH) is a promising alternative approach to DNA sequencing and mutation detection. Analysis of the resolving power of SBH involves rather difficult combinatorial and probabilistic problems, and sometimes computer simulation is the only way to estimate the parameters and limitations of SBH experiments. This paper describes a

Characterization of denaturation and renaturation of DNA for DNA hybridization
Environmental Health and Toxicology, 2014 The present study was designed to systematically characterize the denaturation and the renaturation of double stranded DNA (dsDNA), which is suitable for DNA hybridization.A series of physical and chemical denaturation methods were implemented on well-defined 86-bp dsDNA fragment.

FEBS Letters, EarlyView.We present the cellular transcription‐coupled Flp‐nick system allowing the introduction of a Top1‐mimicking cleavage complex (Flpcc) at a Flp recognition target site within a controllable LacZ gene. LacZ transcription leads to the collision of RNA polymerase II (RNAPII) with Flpcc, and this causes RNAPII stalling, ubiquitination, and degradation.

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to
