Aberrant DNA replication, including over-replication or under-replication may lead to life-threatening mutation or even cause human diseases. This thesis focused on three issues related to abnormal DNA replication in human chromosomes including: I) to define the function of DNA unwinding element (DUE) and DNA unwinding element-binding protein (DUE-B) to maintain an active c-myc replicator; II) to determine the role of trans-acting factors in defining a replication origin on human chromosomes; III) to investigate the mechanism by which hairpins affect DNA replication and instability of (CTG)n•(CAG)n trinucleotide repeat tracts in human cells.

Our laboratory previously demonstrated that both DUE and DUE-B, …
