Coordination of Rad1-Rad10 interactions with Msh2-Msh3, Saw1 and RPA is essential for functional 3' non-homologous tail removal.

Double strand DNA break repair (DSBR) comprises multiple pathways. A subset of DSBR pathways, including single strand annealing, involve intermediates with 3' non-homologous tails that must be removed to complete repair. In Saccharomyces cerevisiae, Rad1-Rad10 is the structure-specific endonuclease that cleaves the tails in 3' non-homologous tail removal (3' NHTR).

A contribution to the history of common salt.

Salt has influenced human nutrition, health, politics, taxation, economy, freight, transport, and commerce throughout the ages. All human activities have been influenced by salt including economy, religious beliefs and practices, art, literature, psychoanalysis, superstitions, and exorcism. Salt is recognized as a symbol for friendship, hospitality, chastity, alliance, table fellowship, fidelity, fertility, blessing, curse and endurance, etc.

Herpes simplex virus type 1 DNA persistence, progressive disease and transgenic immediate early gene promoter activity in chronic corneal infections in mice.

We have used a mouse model system and the corneal route of inoculation to examine the issue of extra-neuronal persistence of herpes simplex virus type 1 (HSV-1). HSV-1 strain F DNA and inflammatory lesions were detected in corneal tissue of mice at 5, 11, 23, 37 and 60 days post-infection (p.i.
