DNA is a double-stranded molecule twisted into a helix (think of a spiral staircase). Each spiraling strand, comprised of a sugar-phosphate backbone and attached bases, is connected to a complementary strand by non-covalent hydrogen bonding between paired bases.

Many teams were interested in being the first to determine the structure of the DNA molecule. Linus Pauling proposed that it was a three chained helix, yet he never really did much research with DNA since he was already deeply involved in other areas of research.
