Chromosome condensation: DNA compaction in real time.
Mitotic chromosomes must be organised into a highly ordered and compacted form to allow proper segregation of DNA during each round of cell division. Two new studies report observations of DNA compaction by eukaryotic and bacterial condensin molecules in real time using magnetic and optical trapping micromanipulation techniques.
