Scientists have detected an important mechanism in the evolution of plant genomes: using Arabidopsis thaliana as a model organism, they studied the formation of tandem repeat DNA sequences and found out that these sequences form if both DNA strands are broken at a significant distance from each other. For their experiments, the scientists used CRISPR/Cas system, working like a 'pair of molecular scissors.'
