The table lists the number of C. briggsae bases in each category. Coding/Intron/Intergenic classification is based on the C. elegans Sequencing Consortium (1998) gene predictions for the corresponding C. elegans regions. Eighty-one percent of the highly conserved bases align to a unique part of the C. elegans genome.
