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...

Question 2a Deoxyribonucleic acid (DNA) is made up of nucleotides. Which part of the nucleotide stabilizes the structure of DNA using weak van der Waals interactions (stacking) and using hydrogen bonds? (Note that covalent bonds are not included in that sentence.) a. the deoxyribose sugar b. the ribose sugar c. the phosphate d. the nitrogenous base e. the amino acid Question 2b This ability of the nitrogenous bases to exist in more than one form can lead to incorporation of...
