The two sides of the DNA double helix are connected by pairs of bases (adenine, thymine, cytosine, and guanine). Because of the geometric shape of these molecules, adenine bonds with thymine and cytosine bonds with guanine. The figure (Figure 1) shows the thymine-adenine bond. Each charge shown is ±e, and the H−N distance is 0.110 nm.A) Calculate the net force that thymine exerts on adenine. To keep the calculations fairly simple, yet reasonable, consider only the forces due to the...

Select the phrases that accurately describe properties of the most common form of the DNA double helix
Select the phrases that accurately describe properties of the most common form of the DNA double helix. There is more than one correct answer. Select all that apply. DNA contains equal amounts of adenine and thymine, and equal amounts of cytosine and guanine. A helical turn consists of about 10 nucleotides. Base pairs have a spacing of 20 A. The phosphodiester bonds between nucleotide residues run in opposite directions in the two strands. The nitrogenous bases are exposed to the solvent, whereas the sugar-phosphate backbone of...
