Mrna

A single-stranded messenger RNA molecule depicted in a clean textbook molecular style as a long, thin, gently wavy linear ribbon or strand. It is unbranched, flexible, and clearly not helical like DNA. The strand shows a repeating sugar-phosphate backbone with small outward-facing nucleotide marks, colored base units, bead-like segments, letters, or codon triplets arrayed along its length. The molecule may include a clear 5′ to 3′ direction, appear as a mature processed RNA without intron segments, and can optionally show a small cap-like end or short tail-like extension.
