From a general biological and #evolutionarybiological perspective, these are very fascinating new findings regarding a previously unknown method of #DNAsynthesis. The well-known process, which students learn about in school, involves #enzymatic processes that split a DNA double helix into two single strands, to which the #polymerase adds a #complementary #sequence. In this way, the original DNA helix is #replicated base by base. However, the authors P. Deng et al. (2026) have now discovered a significantly different DNA synthesis method: In the bacterial model organism #Escherichia #coli, it was found that the #enzyme #Drt3b does not require a DNA or RNA template for synthesis. Instead, a complementary, protein-primed #polyACstrand is synthesized without a #nucleicacid template. The enzyme uses information contained within itself to avoid the need for a DNA template. These are conserved #aminoacidresidues specific to Drt3b, located in its #activesite to generate the necessary base sequence. Characteristics of life are always a result of #evolution. The enzyme Drt3b uses its synthesis mechanism to synthesize a DNA sequence that can defend #againstviruses. This text by Stefan F. Wirth, April 2026, Berlin Reference: P. Deng et al.
