But by investigating the DNA sequence around the resistance genes, the team figured out how the resistance genes transfer occurred through a new mechanism named «carry back,» where the pathogen basically has a primitive form of «sex» with the Actinobacterium and takes up its resistance genes after it dies.
Not exact matches
With respect to antibiotic resistance, this novelty can be induced and we can trace the novelty to particular mutations arising absent gene transfer; i.e. the genes which give rise the resistance were not present prior to the mutation, they are new sequences and not simply the activation of dormant genes.
