We report the generation and analysis of functional data from multiple, diverse experiments performed on a targeted 1% of the human genome as part of the pilot phase of the ENCODE Project. These data have been further integrated and augmented by a number of evolutionary and computational analyses. Together, our results advance the collective knowledge about(More)
DNA replication in metazoans initiates from multiple chromosomal loci called origins. Currently, there are two methods to purify origin-centered nascent strands: lambda exonuclease digestion and anti-bromodeoxyuridine immunoprecipitation. Because both methods have unique strengths and limitations, we purified nascent strands by both methods, hybridized them(More)
Chromosomes in human cancer cells are expected to initiate replication from predictably localized origins, firing reproducibly at discrete times in S phase. Replication products obtained from HeLa cells at different stages of S phase were hybridized to cDNA and genome tiling oligonucleotide microarrays to determine the temporal profile of replication of(More)
Effective reproduction is essential for the survival and proliferation of any organism, from the birth of new offspring to the reproduction of individual cells. Each portion of a cell's DNA must be copied exactly once during the replication phase of its cell cycle to ensure viability. In humans, this is achieved by a complex pattern of replication origins(More)
