“Junk” DNA story for today

‘Junk’ DNA makes compulsive reading

Whatever the truth, the results pose fresh puzzles about how genes work. “It would now take a very brave person to call non-coding DNA junk,” says Greally.

It would. So stop it, New Scientist. Putting the “junk” in quotation marks doesn’t distract us from the usage of the word.

The article is a summary of recent findings from the ENCODE project (ENCyclopedia Of DNA Elements). More details in:
