Zinc regulates the stability of repetitive minisatellite DNA tracts during stationary phase.
Repetitive minisatellite DNA tracts are stable in mitotic cells but unstable in meiosis, altering in repeat number and repeat composition. As relatively little is known about the factors that influence minisatellite stability, we isolated mutations that destabilize a minisatellite repeat tract in the ADE2 gene of Saccharomyces cerevisiae. One mutant class exhibited a novel color segregation phe...
متن کاملMultiple Pathways Regulate Minisatellite Stability During Stationary Phase in Yeast
Alterations in minisatellite DNA repeat tracts in humans have been correlated with a number of serious disorders, including cancer. Despite their importance for human health, the genetic factors that influence minisatellite stability are not well understood. Previously, we identified mutations in the Saccharomyces cerevisiae zinc homeostasis genes ZRT1 and ZAP1 that significantly increase the f...
متن کاملA Whole Genome Screen for Minisatellite Stability Genes in Stationary-Phase Yeast Cells
Repetitive elements comprise a significant portion of most eukaryotic genomes. Minisatellites, a type of repetitive element composed of repeat units 15-100 bp in length, are stable in actively dividing cells but change in composition during meiosis and in stationary-phase cells. Alterations within minisatellite tracts have been correlated with the onset of a variety of diseases, including diabe...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Sequencing homopolymer tracts and repetitive elements.
We investigated the use of Taq dye primer and Taq terminator sequencing chemistry to optimize the quality of sequence data obtained from templates containing homopolymer tracts and repetitive elements. In direct side-by-side comparisons using the Applied Biosystems Model 373A Fluorescent Sequencer, the Taq terminator sequencing chemistry gave much cleaner and more consistent results on long hom...
