Humans could regrow limbs as scientists uncover a 'DNA switch

Scientists have discovered that non-coding or 'junk' DNA controls regeneratio
Full-body regeneration is seen in jellyfish, sea anemones, and planarian worms
'Junk' DNA controls the activation of a gene called early growth response (EGR)
Humans have EGR to repair cells but it doesn't trigger large scale regeneration
Researchers are now trying to change the gene so that we too can 'regenerate
