Figure 1.

Repetitive sequence elements in the C.elegans genome with asymmetrical distributions. The genome-wide distribution of each of the six repetitive elements described in the text are shown. Each chromosome is labeled with roman numerals on the left side of the panels. Horizontal rectangular boxes represent the six worm chromosomes. Caenorhabditis elegans gene names for genetic markers used to orient the physical map are shown above the chromosomes. The shaded portions of each chromosome correspond to genetically mapped HRR/MPC elements (4). Each panel shows the location of individual CeRep elements. Black vertical lines represent the locations along the chromosomes. Chromosomes vary in length from ∼13 to ∼21 Mb and are normalized in this diagram. The scale is shown along the bottom of each panel.
