Scientists use the term "stalled forks" for areas of replication forks where DNA polymerization is halted. Stalled forks activate ATR, which in turn phospohorylates its downstream target ...
Dr. Tsubouchi concludes, "We propose that slow replication forks are not the manifestation of replication impediments but rather an integral feature of DNA replication in ES cells.
Homologous recombination plays essential roles in the repair of DNA double strand breaks (DSBs) and collapsed replication forks. The fundamental reaction in homologous recombination is the exchange of ...
