Figure 5.

Overcoming evolution barrier (shown in figure 4). Stage where the (+)-R-strand's message is translated by the HAE_RD- device into enzyme E_RD (specific sequence) while the D-strands do not form HAE-devices (as it is in biology: in contrast to RNA, DNA does not form a translation device). It cooperates with a similar device, where the translation product is enzyme E_DR (not shown).
