Pre mrna

Single-stranded eukaryotic pre-mRNA shown as a long, flexible, mostly linear to gently wavy RNA strand, longer and less refined than mature mRNA. The molecule has clearly segmented regions with alternating exon and intron sections indicated by contrasting colors or highlighted blocks connected by intervening segments. It may include visible nucleotide units or small marks along the backbone, and labeled 5′ and 3′ ends. The strand is unspliced and lacks mature end modifications or attached ribosomes, conveying a freshly synthesized, not-yet-fully-processed transcript. Exon and intron regions are visually distinguished.
