Abstract:
:We have developed a new and rapid immunofluorescent method for visualisation of replicated regions on fixed DNA fibers. Using this method we have found in 5-fluorodeoxyuridine (FrdU)-blocked human cells distinct replication units covering about 60 kb of DNA and corresponding in size to single replicons or chromatin loops. Our results also suggest that nonadjacent replicons within a replicon cluster may be activated after FrdU arrest and that the method may be adapted for localization on fibers of specific DNA sequences.
