O.o!!!!!
Changing the number of chromosomes an animal has can take millions of generations to happen in nature through the course of evolution – and now, scientists have been able to make these same changes in lab mice in a relative blink of an eye.
The new technique using stem cells and gene editing is a major accomplishment, and one that the team is hoping will reveal more about how the rearrangement of chromosomes can influence the way that animals evolve over time.
It’s in chromosomes – those strings of protein and DNA inside cells – that we find our genes, inherited from our parents and blended together to make us who we are.
