DNA May Have Had Humble Beginnings As Nutrient Carrier
Moffet Field CA (SPX) Sep 08, 2014 - New research intriguingly suggests that DNA, the genetic information carrier for humans and other complex life, might have had a rather humbler origin. In some microbes, a study shows, DNA pulls double duty as a storage site for phosphate. This all-important biomolecule contains phosphorus, a sometimes hard-to-get nutrient. Maintaining an in-house source of phosphate is a newfound tactic f ... more
