Project description:Array data detailing the progression of DNA replication in the yeast Lachancea waltii. L. waltii cells were pregrown in heavy isotope medium and synchronized at early S phase. They were then released into normal medium, wherein DNA replication proceeds. Replicated DNA molecules are thus of heavy-light (HL) composition as compared to unreplicated molecules, which are heavy-heavy (HH). 4 time points were taken and the percent of heavy-light DNA was determined at each time point. The heavy-heavy and heavy-light DNA molecules were separated by ultracentrifugation, differentially labeled, and hybridized to a genomic array for L. waltii. The array thus shows the progression of DNA replication.
Project description:Haploid cells of Lachancea kluyveri were arrested in G1 phase using Saccharomices cerevisiae alpha factor. After, release in a new media, cells go synchronously through S-phase. One sample is taken every five minutes. Microarrays are used to monitor the change of DNA copy number from 1 to 2, all along the genome during S-phase. Two-condition experiment, G1 cells vs. S-phase cells at different time points. Biological replicates: 3 biological replicates.
