Lagging Steps Traced in DNA Replication
To pass along genes, dividing cells must duplicate their genomes. Complicating this everyday routine, the strands are replicated in a lopsided process. Researchers in the lab of Antoine van Oijen (center), including Samir Hamdan (left) and Joe Loparo, have observed the dynamic loop-and-release exploits of lagging-strand replication by studying hundreds of duplicating DNA strands, one at a time. Their single-molecule analysis establishes the molecular events that regulate loop growth and release, revealing new feats of timing and technique in a famously thorny aspect of DNA replication.
