Furthermore, since all organisms contain a slightly different genetic code, their mRNA structures differ slightly as well, however, multiple studies have been conducted that show that all properly folded mRNA structures are dependent on the primary sequence of the polypeptide chain and that the structure is maintained by dinucleotide relative abundances in the cell matrix. It has also been discovered that mRNA secondary structure is important for cell processes such as transcript stability and translation. The general idea is that the functional domains of mRNA fold upon each other, while the start and stop codon regions generally are more relaxed, which could aid in the signaling of initiation and termination in translation.[1]
