Minerva Shield A chromosome (blue) imaged during cell replication. The chromosome is duplicated, and protein strands called spindle fibers (red) are attached to the chromosome copies to pull them apart, so that each ‘daughter cell’ gets one copy. The spindle fibers attach to the chromosomes due to the centromere.
