Meiotic and mitotic behavior of dicentric chromosomes in Saccharomyces cerevisiae.
Meiotic recombination between a circular and a linear chromosome in Saccharomyces cerevisiae has been investigated. The circle was a haploid-viable derivative of chromosome III constructed by joining regions near the two chromosome ends via a recombinant DNA construction: (HMR/MAT-URA3-pBR322-MAT/HML) and was also deleted for MAL2 (which therefore uniquely marks a linear chromosome III). Recomb...
متن کاملSaccharomyces Cerevisiae as a Biocatalyst for Different Carbonyl Group under Green Condition
In this researchsaccharomyces cerevisiae (baker’s yeast) was used as a cheap, readily accessible, selective, efficient, and green bio-catalyst in a chemo selective reduction of carbonyl group to hydroxyl group. In this green procedure three substrates e.g. (3-(3-nitrophenyl)aziridin-2-yl)-1-phenyl-methanone, pyruvate ester, and 2-acetyl-γ-butyrolactone were r...
متن کاملMixed segregation of chromosomes during single-division meiosis of Saccharomyces cerevisiae.
Normal meiosis consists of two consecutive cell divisions in which all the chromosomes behave in a concerted manner. Yeast cells homozygous for the mutation cdc5, however, may be directed through a single meiotic division of a novel type. Dyad analysis of a cdc5/cdc5 strain with centromere-linked markers on four different chromosomes has shown that, in these meioses, some chromosomes within a g...
متن کاملG+C content variation along and among Saccharomyces cerevisiae chromosomes.
Past analyses of the genome of the yeast Saccharomyces cerevisiae have revealed substantial regional variation in G+C content. Important questions remain, though, as to the origin, nature, significance, and generality of this variation. We conducted an extensive analysis of the yeast genome to try to answer these questions. Our results indicate that open reading frames (ORFs) with similar G+C c...
متن کاملSir protein–independent repair of dicentric chromosomes in Saccharomyces cerevisiae
Sir2 protein has been reported to be recruited to dicentric chromosomes under tension, and such chromosomes are reported to be especially vulnerable to breakage in sir2Δ mutants. We found that the loss of viability in such mutants was an indirect effect of the repression of nonhomologous end joining in Sir(-) mutants and that the apparent recruitment of Sir2 protein to chromosomes under tension...
