Question
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. A helical turn consists of about 10 base pairs. The phosphodiester bonds between nucleotide residues run in opposite directions in the two strands. The sugar-phosphate backbone is exposed to the solvent, whereas the nitrogenous bases are in the interior of the double helix. DNA contains equal amounts of adenine and guanine (the purines), and equal amounts of cytosine and thymine (the pyrimidines). Base pairs have a spacing of 20 A.Explanation / Answer
Answer:
1 to 4 are the properties of the DNA double helix.
5th one is not property because 20 Å unit is diameter of the helix not spacing.
