Which statements reflect the Watson-Crick model of DNA? Select all that apply. The strands of DNA run in the same direction. Two helical DNA strands are coiled around a common axis, forming a right-handed double helix. The sugar-phosphate backbone lies outside of the helix. The diameter of the helix is 30 Å. The purine and pyrimidine bases lie outside of the helix.
