Base sequence of a non-self-complementary messenger RNA of human heart cytochrome

The messenger RNAs of 72 natural proteins built using only the first two bases of their animo acid codons show that antiparallel auto-complementarities of four or more successive bases are avoided. Supported by this fact, the third base of each codon of the mRNA of human heart cytochrome c was selected, choosing every time (with a computer) that base which induced the lowest number of antiparallel anti-complementarities of four or more successive bases with all the nucleotides of the rest of messenger. The cytochrome messenger found has no antiparallel auto-complementarity of five or more successive bases and only 51 of four. Thus at 37 °C, a monotenic structure of messenger would be preferred.
