The TOP sequences. TOP sequences are close to the translation start codon of ribosomal protein genes across all Drosophila species (Panel A). Here y-axis represents the number of RPG genes having TOP motif at a given distance from the translation start codon as shown in x-axis. For each ribosomal protein gene, its TOP motif is defined as the best matching sequence in the upstream 1 kb region using the estimated position weight matrix in corresponding species, which is shown in panel B.
