<em>C. elegans</em> with Defective eri-1 Gene

Caption

Roundworms (Caenorhabditis elegans) with a disabled eri-1 gene can lose their ability to control repetitive DNA. In the absence of eri-1, even two age-matched siblings can look dramatically different. These differences are because of variable expression from high-copy DNA (green) but not from low-copy DNA (magenta) in the worms’ intestinal cells. In worms with a functional eri-1 gene, even multi-copy DNA is expressed uniformly in all animals. Image credit: Antony Jose (Click image to download hi-res version.)
