Primary rna transcript

Freshly synthesized primary RNA transcript shown as a long single-stranded, thin flexible ribbon-like molecule with a slightly wavy or gently curved course. The strand is linear overall, thinner than DNA, lacking any paired double-helix structure, 5' cap, or poly-A tail, and appearing unspliced and immature. Exon and intron regions are indicated along its length as alternating colored blocks or segmented regions connected within the same strand, making it appear longer and less compact than mature mRNA. The molecule may include small nucleotide marks and subtle mixed straight and looped portions.
