Each of the following statements about the structure of DNA may be either true or false. Choose the appropriate answer for each of these statements. Bonding between adenine and thymine on opposite strands involves two hydrogen bonds. Nitrogenous bases are located on the outside of the double helix: phosphates are located towards the middle of the double helix. Bonding between guanine and cytosine on opposite strands involves three hydrogen bonds. DNA and RNA are structurally different due to the difference...
