Why scientists watched a gene hop from a predator into its prey
Researchers at the Max Planck Institute have observed an RNA molecule jumping between a predatory bacterium and its archaeal prey. This rare event provides new insights into horizontal gene transfer and the evolution of transposable elements.
Why it matters
Understanding how genes move between species has significant implications for medicine, particularly in addressing antibiotic resistance and developing new vaccine platforms.
Since scientists discovered jumping genes in maize in 1950, they have known that bits of DNA can move around the genome, mostly within the cell nucleus. Scientists have also found evidence of genes having jumped across species .
Now, researchers at the Max Planck Institute for Marine Microbiology in Germany have reported a remarkable observation : they have visually tracked an RNA molecule, called an intron, as it jumped from one organism into another.
This is remarkable because the scientists literally caught the gene as it jumped across species, without the help of any courier.
