XI.6.2 Sequences of repetitive motifs reflect some characteristics of the genetic code; they probably developed only after the present-day proteosynthetic apparatus was established

The sequences of oligonucleotides, from which genes are or most probably were composed, reflect some of the properties of the present-day genetic code and the present-day proteosynthetic apparatus.The presence of these repeating motifs could simultaneously be a result of the biological evolution of genes and could be of adaptive importance for organisms.

The classical Darwinian theory of evolution can explain the evolution of adaptive traits only in asexual organisms. The frozen plasticity theory is much more general: It can also explain the origin and evolution of adaptive traits in both asexual and sexual organisms Read more
