From: Genome-wide analysis of chicken snoRNAs provides unique implications for the evolution of vertebrate snoRNAs

Figure 4

Comparison of the structure of snoRNAs encoded in the human gas5 and chicken gas5 -like host gene (A) and analysis of the protein-coding potential of human (Accession No. AF141346) and chicken (mRNA CR387333) transcripts (B). (A) The exons and snoRNA regions (not drawn to scale) are denoted by black and gray boxes, respectively. The snoRNA names are indicated. The snoRNA counterparts between chicken and human are indicated by the same Roman numerals. The exon regions are indicated by Arabic numerals in order. The TATA elements are boxed; the transcription start sites are indicated in bold and the 5' TOP sequences are underlined. (B) Coding potential of human and chicken transcripts identified by the BLAST ORF Finder http://www.ncbi.nlm.nih.gov/projects/gorf/gorf.html. Short and long vertical bars represent start and stop codons, respectively, in all three frames. The gray boxes denote the most likely reading frames.
