Figure 1. Physical map (Pmap) of a region in the Caenorhabditis elegans genome showing the tiling path of yeast artificial chromosome (YAC) clones (upper region A), cosmid/fosmid mapping (middle region B) and mapped genetic loci (bottom region C).

Figure 2. Schema for the analysis pipeline used in the analysis of the C. elegans genome sequence. Finished sequence from the sequence editors GAP4 and CONSED is subjected to a number of computational algorithms (similarity searches, repeat matches and gene predictions). Data are consolidated in the ACEDB database and evaluated by an annotator. The sequence with its annotations is then submitted to the public nucleotide databases (EMBL/GenBank).

Figure 3. Sequence display (Fmap) for a region of the C. elegans genome showing two gene predictions. Coding exons, connected by introns, are displayed to the right of the scale. The extent of transcript data is indicated by the rectangles to the right of the gene prediction. Similarity data are displayed in the next columns, reading from left to right: C. elegans expressed sequence tag, worm peptide, fly peptide, yeast peptide, human peptide, other peptides and C. briggsae genomic matches. The two columns on the far right indicate the location of repeats in this sequence region.
