RescueMu, a Mu1 element containing a bacterial plasmid, is mobilized by MuDR in transgenic maize. Somatic excision from a cell-autonomous marker gene yields >90% single cell sectors; empty donor sites often have deletions and insertions, including up to bp of RescueMu/Mu1 terminal DNA. Late somatic insertions are contemporaneous with excisions, suggesting that “cut-and-paste   cover computational simulation of DNA damage induction and repair processes, modeling of carcinogenesis process, experimental characterization of DNA damages, study on bystander effect utilizing micro beam technique, molecular biology study of radioresistant bacterium Deinococcus radiodurans.

Title(s): Selected abstracts on excision repair of DNA damage/ Michael A. Sirover, consulting :// Abstract. Despite a longstanding understanding that many endogenous and exogenous agents can damage DNA, knowledge of how DNA repairs itself was largely an academic pursuit until the last two decades.

The ongoing molecular characterization of the DNA damage response (DDR) and pathway crosstalk is invaluable in helping scientists learn how to modulate DNA repair activities therapeutically BRCA1 is a key mediator of DNA repair pathways and participates in the maintenance of the genomic integrity Selected abstracts on excisions repair of DNA damage book cells.
