The single-stranded DNA (ssDNA)-binding protein replication protein A (RPA) is essential for both DNA replication and recombination. Chromatin immunoprecipitation techniques were used to visualize the kinetics and extent of RPA binding following induction of a double-strand break (DSB) and during its repair by homologous recombination in yeast. RPA assembles at the HO endonuclease-cut MAT locus...
The ability to induce synchronously a single site-specific double-strand break (DSB) in a budding yeast chromosome has made it possible to monitor the kinetics and genetic requirements of many molecular steps during DSB repair. Special attention has been paid to the switching of mating-type genes in Saccharomyces cerevisiae, a process initiated by the HO endonuclease by cleaving the MAT locus. ...
Mitotic double-strand break (DSB)-induced gene conversion at MAT in Saccharomyces cerevisiae was analyzed molecularly in mutant strains thermosensitive for essential replication factors. The processivity cofactors PCNA and RFC are essential even to synthesize as little as 30 nucleotides following strand invasion. Both PCNA-associated DNA polymerases delta and epsilon are important for gene conv...
The inaccurate repair of DNA double-strand breaks (DSBs) can result in genomic instability, and additionally cell death or the development of cancer. Elg1, which forms an alternative RFC-like complex with RFC2-5, is required for the maintenance of genome stability in Saccharomyces cerevisiae, and its function has been linked to DNA replication or damage checkpoint response. Here, we show that E...
A direct shear cell to measure the shear strength and flow properties of chopped switchgrass, wheat straw and corn stover was designed, fabricated, and tested. The shear strength measured at various normal stresses was found to be significantly different. Shear strength for all three chopped biomass types measured at a particular normal stress was not significantly different. The R value of the...
