What if everything you learned about DNA replication is only part of the story?In this episode, we explore a groundbreaking discovery that’s reshaping how scientists think about genetic information. Researchers have identified a bacterial enzyme that can build DNA without using an existing DNA or RNA template. Instead, it uses its own protein structure as a guide—something that challenges the traditional “central dogma” of biology.We break down how this system, known as DRT3, may help bacteria defend themselves against viral invaders by producing repetitive DNA sequences that act as molecular decoys or signals. It’s a fascinating glimpse into the hidden complexity of microbial life and a reminder that biology still has plenty of surprises left.We also dive into what this could mean for the future. Could this discovery lead to new tools in synthetic biology? Custom-built DNA materials? Even entirely new ways of engineering biological systems?In this episode:A new way to think about DNA synthesisHow proteins can act as templatesBacterial defense strategies against virusesThe future of synthetic biology and biomaterialsThis discovery doesn’t rewrite the genetic code—but it does expand the rules we thought were fixed.Source: https://www.science.org/content/artic...#Biology #Genetics #DNA #SciencePodcast #Microbiology #SyntheticBiology #Biotech #scienceexplained
