Replication profiles for wild type and Dbf4-9myc S.cerevisiae samples

Description

Replication profiles for wild type and Dbf4-9myc samples (T7107 and T9394 strains). The cells were stained with DNA dye and sorted based on DNA content into S or G2/M phase fractions. Extracted DNA was sequenced and mapped to sacCer3 genome. Unique reads for replicating (S) and non-replicating (G2/M) samples were calculated in 1 kb genomic bins. The ratio was created by dividing 'score' values from replicating sample by non- replicating sample 'score' values, adjusted by total number of reads. The ratio values were further adjusted by multiplying them by 1.41 and 1.402 for wild type and Dbf4-9myc samples, respectively, to put the values onto biologically relevant relative copy number scale from 1 to 2. The relative copy number values were smoothed using cubic spline and compared using z score statistics.
