A DNA molecule consists of two antiparallel strands of polynucleotides. Each strand is composed of nucleotides bound to each other along the sugar-phosphate backbone. Drag "True" or "False" to the end of each statement. In a single nucleotide, the phosphate group is attached to the 5' carbon of the sugar unit. True Complementary base pairing relies on the number of hydrogen bonds that each base can make. True The -OH group on the 3' carbon of the sugar unit is the attachment site for the nitrogenous base. False The phosphate attached to the 5' carbon of a given nucleotide links to the 3' -OH of the adjacent nucleotide. True The antiparallel arrangement of double-stranded DNA is due to the phosphate group being bonded to the 3' carbon on one strand and the 5' carbon on the complementary strand. True

1. (True or False) Adjacent nucleotides are joined by covalent bonds that form between the –OH group on the 3' carbon of one nucleotide and the phosphate on the 5' carbon of the next. 2. (True or False) If a solute is in an aqueous solution, then by definition, a hydration shell has formed around it. 3. (True or False) When exposed to water, phospholipids will self-organize into lipid bilayers and spheres.
