Low‐copy nuclear genes were used to address the notoriously difficult phylogeny of Ephedra. Additionally, we explored the potential effect of putative paralogy, intra‐locus recombination, and chimeric sequences on phylogenetic estimation. ABSTRACT The evolutionary history of Ephedra L.

The Schizosaccharomyces pombe mag1 gene encodes a DNA repair enzyme with sequence similarity to the AlkA family of DNA glycosylases, which are essential for the removal of cytotoxic alkylation products, the premutagenic deamination product hypoxanthine ...

Cellular location and activity of Escherichia coli RecG proteins shed light on the function of its structurally unresolved C-terminus [PDF]
RecG is a DNA translocase encoded by most species of bacteria. The Escherichia coli protein targets branched DNA substrates and drives the unwinding and rewinding of DNA strands.

Genetic landscape of open chromatin in yeast. [PDF]
Chromatin regulation underlies a variety of DNA metabolism processes, including transcription, recombination, repair, and replication. To perform a quantitative genetic analysis of chromatin accessibility, we obtained open chromatin profiles across 96 ...

Retaining Models of Human Evolution After Repeated Falsifications—Why?
Two 19th century paradigms of human evolution emerged: Humans are subdivided into isolated populations in an evolutionary tree, versus human populations interbreed (gene flow) with no isolates. The tree model has been rejected whenever tested since the 1970's, whereas gene flow consistently fits.

SJG-136, a pyrrolo[2,1-c][1,4]benzodiazepine (PBD) dimer, is a highly efficient interstrand crosslinking agent that reacts with guanine bases in a 5'-GATC-3' sequence in the DNA minor groove.

Mu insertions are repaired by the double-strand break repair pathway of Escherichia coli. [PDF]
Mu is both a transposable element and a temperate bacteriophage. During lytic growth, it amplifies its genome by replicative transposition. During infection, it integrates into the Escherichia coli chromosome through a mechanism not requiring extensive ...

ABSTRACT Canine congenital cleft palate is one of the most common craniofacial anomalies in dogs, characterized by a failure of the palatal shelves to fuse properly during fetal development, leading to abnormal communication between the oral and nasopharyngeal cavities.
