WebPARP1 is a protein that is important for repairing frequently occurring single-strand breaks (“nicks”) in the DNA which occur in the cell cycle. If such nicks persist unrepaired until DNA is replicated (which must precede cell division), then the replication itself can cause double-strand breaks to form [29].
