This track integrates genome-wide datasets related to DNA replication, including Repli-seq and OK-seq. Repli-seq measures replication timing across the genome by profiling newly synthesized DNA from cells isolated at different stages of S phase, whereas OK-seq maps replication fork directionality based on the distribution of Okazaki fragments. Together, these datasets provide complementary information on replication timing, fork progression, and the organization of DNA replication across the genome.
