Eukaryotic gene

A linear schematic of a eukaryotic gene drawn as a horizontal double-stranded DNA segment with clear upstream-to-downstream orientation. Near one end is a small promoter region, followed by untranslated regions and several separated exon blocks shown as thicker colored rectangles connected by thinner intron lines. The coding portion is distributed across the exon blocks rather than being continuous, and the gene ends in a downstream terminal region that includes a marked poly-A signal sequence. The overall figure is an organized DNA-based diagram using distinct colors to differentiate functional segments and emphasize the alternating exon-intron structure.
