A chromosome 'zipper' conserved across evolution (IMAGE)
Caption
During meiosis, a ladder-like structure called the synaptonemal complex forms between paired chromosomes. In Nematostella, the structure looks remarkably similar to the one found in vertebrates and contains many of the same protein components. The new study shows, however, that some of those familiar-looking parts can perform different jobs.
