Figure 1.

A standard view in Apollo, showing a 250 kb segment of Drosophila chromosome arm 2L. The background colors for the result (gray), annotation (light blue) and sequence (white) panels are configurable. The features and annotations on the forward strand are shown above the white sequence panel, and those on the reverse strand are shown below it. There are seven tiers (or rows) of data presented here in the results panel (the number of tiers is configurable). On the forward strand from top to bottom these results are promoter predictions (yellow), P-element insertions (turquoise triangles), peptide homologies to other species (orange), peptide homologies to Drosophila (red), Drosophila EST alignments (light green), Drosophila mRNA alignments (bright and dark green) and gene prediction results (lavender). The genomic region navigation bar is above the data displays and the navigational and zoom controls for the current genomic region in the display are below. The user may increase the genomic region visible in the display by using the 'Expand' button. They may also move to adjacent regions by clicking on the '<' (5' upstream) and '>' (3' downstream) buttons or move to entirely new regions by changing the chromosome arm and the start and end positions. Within the display the most basic movement operations (zooming and scrolling) are available from the controls at the bottom of the display.
