WebThe replication fork is a region where a cell's DNA double helix has been unwound and separated to create an area where DNA polymerases and the other enzymes involved … WebOur results demonstrate that a reversible replication fork barrier allows induction of a synchronous and spatially defined termination event. They also show that soon after forks meet, as measured by dissolution, daughter molecules are quickly ligated and decatenated. Converging replication forks do not stall

WebApr 10, 2024 · Here, we demonstrate that the ubiquitin ligase RFWD3, whose mutation causes Fanconi Anemia, promotes recruitment of the DNA translocase ZRANB3 to stalled replication forks and ubiquitinated sites of DNA damage. Using electron microscopy, we show that RFWD3 stimulates fork remodeling in a ZRANB3-epistatic manner.
