Structural and genetic analysis of X-ray scattering by spores of Bacillus subtilis.

abstract：:The Saccharomyces cerevisiae gene MEC1 represents a structural homolog of the human gene ATM mutated in ataxia telangiectasia patients. Like human ataxia telangiectasia cell lines, mec1 mutants are defective in G2 and S-phase cell cycle checkpoints in response to radiation treatment. Here we show an additional defect ...
