title: Input data of UV-treated hela-s3 in early S phase, replicate 1
design: HeLa cells were irradiated with UV at 1.5 or 3.5 hours after                 releasing to the S phase, then incubated with a medium containing EdU for 2 hours                 before harvesting. Genomic DNA were fragmented by sonication and biotin-labeled by                 click reaction, then end-repaired and ligated to the adaptor with NEBNext Ultra II                 DNA library preparation kit according to the manufacturer's instructions. One                 percent of each sample was amplified for input sequencing. Resulting libraries were                 sequenced by the Illumina NovaSeq system.
