Incorporating each set of daughter chromosomes into a single nucleus at the end of mitosis is essential for genome stability. In a recent Cell paper, Samwer et al. (2017) show that by non-covalently crosslinking DNA, BAF promotes chromosome coalescence, preventing nuclear membranes from enwrapping individual chromosomes to form micronuclei.
