We tested it on an amazing bacterium that lives inside marine algae and is exceptionally good at mixing and matching its DNA. We found the genes responsible for this ability and showed that when we put them into common laboratory bacteria, they gained this enhanced DNA-recombination ability too. This discovery is exciting because it gives scientists both a new way to find special genes in any bacteria and new tools that could make genetic engineering more efficient in laboratories around the world. |
