Using the Electronegativities we can predict whether a given bond will be non-polar, polar covalent, or ionic. The greater the difference in electronegativity the more polar the bond.
DNA is a polymer of nucleotides. Two polymers can join to form a double-stranded molecule (double helix) via complimentary base pairing. For more details go to the "DNA structure and function" board
