Molecular biology and evolution, 1993 Examining the pattern of nucleotide substitution for the control region of mitochondrial DNA (mtDNA) in humans and chimpanzees, we developed a new mathematical method for estimating the number of transitional and transversional substitutions per site, as

Structural insights into the gating of DNA passage by the topoisomerase II DNA-gate. [PDF]
, 2018 Type IIA topoisomerases (Top2s) manipulate the handedness of DNA crossovers by introducing a transient and protein-linked double-strand break in one DNA duplex, termed the DNA-gate, whose opening allows another DNA segment to be transported through to ...

FlavonoidSearch: A system for comprehensive flavonoid annotation by mass spectrometry
Scientific Reports, 2017 Currently, in mass spectrometry-based metabolomics, limited reference mass spectra are available for flavonoid identification. In the present study, a database of probable mass fragments for 6,867 known flavonoids (FsDatabase) was manually constructed ...

Cyclization of Short DNA Fragments [PDF]
Physica A482, 569 (2017), 2017 From the per unit length free energy for DNA under tension, we have calculated an effective contour length dependent persistence length for short DNA. This effective persistence length results from the enhanced fluctuations in short DNA. It decreases for shorter DNA, making shorter DNA more flexible.

A simple salting out procedure for extracting DNA from human nucleated cells.
Nucleic Acids Research, 1988 One of the obstacles encountered when extracting DNA from a large number of samples is the cumbersome method of deprotein-izing cell digests with the hazardous organic solvents phenol and isochloroform.

AFLP: a new technique for DNA fingerprinting.
Nucleic Acids Research, 1995 A novel DNA fingerprinting technique called AFLP is described. The AFLP technique is based on the selective PCR amplification of restriction fragments from a total digest of genomic DNA.

DNA polymorphisms amplified by arbitrary primers are useful as genetic markers.
Nucleic Acids Research, 1990 Molecular genetic maps are commonly constructed by analyzing the segregation of restriction fragment length polymorphisms (RFLPs) among the progeny of a sexual cross.
