The Lewis dot structure for molecular oxygen (O2) is shown below. Note, O2 exists as drawn with unpaired electrons on each oxygen atom. Using your understanding of formal charge, what is the charge on the oxygen atoms? F=Z–(1/2)S–U, where F=formal charge, Z=atomic number, S=number of shared electrons, U=number of unshared electrons.

The discovery of the structure of double-stranded DNA led to the 1962 Nobel Prize in Physiology and Medicine for James Watson, Francis Crick, and Maurice Wilkins. However, DNA can also form a quadruplex structure with guanidines, which is believed to assist in regulating gene transcription. In the quaduplex shown below, what interaction stabilizes the quadruplex structure?
