junk dna apparently not “junk”

Breakthrough study overturns theory of ‘junk DNA’ in genome

“Long stretches of DNA previously dismissed as “junk” are in fact crucial to the way our genome works, an international team of researchers said on Wednesday. It is the most significant shift in scientists’ understanding of the way our DNA operates since the sequencing of the human genome in 2000, when it was discovered that our bodies are built and controlled by far fewer genes than expected. Now the next generation of geneticists have updated that picture.”
