WebHere, we report a single-cell DNA replication sequencing method, scRepli-seq, a genome-wide methodology that measures copy number differences between replicated and unreplicated DNA. Using scRepli-seq, we demonstrate that replication-domain organization is conserved among individual mouse embryonic stem cells (mESCs). WebIntroduction. Eukaryotic cells must complete DNA replication before chromosome segregation in order to maintain genomic stability.
