A general feature of the nucleus is the organization of repetitive deoxyribonucleic acid sequences in clusters concentrating silencing factors. In budding yeast, we investigated how telomeres cluster in perinuclear foci associated with the silencing complex Sir2-Sir3-Sir4 and found that Sir3 is limiting for telomere clustering. Sir3 overexpression triggers(More)
Gene replacement was achieved by homologous recombination in Mycobacterium smegmatis (Ms) using a cloned segment of the polA gene (encoding the DNA polymerase I) disrupted within the region encoding the C-terminal DNA polymerase domain by a kanamycin-resistance marker. The Ms polA755:aph mutant thus generated displayed a phenotype of hypersensitivity to DNA(More)
