Description Usage Format Source References Examples

Description

Replication profiles of wild type S. cerevisiae arrest-release samples (AUY077 strain). The cells were arrested in G1 with alpha-factor followed by release using pronase. The samples were collected before the release (aFactor) and various time intervals after the release (25min,30min,35min,40min,45min,50min and 90min) Extracted DNA was sequenced and mapped to sacCer3 genome. Unique reads for replicating (post-release) and non-replicating (aFactor) samples were calculated in 1 kb genomic bins. The ratios were created by dividing 'score' values from replicating samples by non-replicating sample 'score' values, adjusted by total number of reads. The ratio values were further adjusted based on bulk genome replication (as determined by flow cytometry), 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.
