Summary of Meeting:
The Keystone Symposia “DNA Replication and Recombination” meeting, the longest standing meeting of this multi-decade series continues to meld investigators representing a range of disciplines who otherwise would not have a format for sharing novel approaches and groundbreaking discoveries. This field drives DNA sequencing technology, the design of myriad anti-viral and anti-bacterial drugs, and the development of novel strategies for gene targeting and generation of transgenic animals. Major pivotal questions include (1) the role of condensins in DNA pairing and replication fork movement, (2) mechanisms by which stalled replication forks are recognized and replication is restarted, (3) the role of recombinational mechanisms in the maintenance of telomeres in the absence of telomerase, (4) the architecture of forks and replication origins, and (5) the mechanisms by which fork initiation is timed with the cell cycle. Speakers representing established laboratories will share the podium with young investigators describing genomic, structural, and biochemical approaches to these central questions.
