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.
