When nucleotides polymerise to form a nucleic acid, ________.
A) a covalent bond forms between the sugar of one nucleotide and the phosphate of a second
B) a hydrogen bond forms between the sugar of one nucleotide and the phosphate of a second
C) covalent bonds form between the bases of two nucleotides
D) hydrogen bonds form between the bases of two nucleotides

Question

Quizplus · Accepted Answer

When nucleotides polymerize to form a nucleic acid, a covalent bond forms between the sugar of one nucleotide and the phosphate of a second, creating a sugar-phosphate backbone. The bases then project from this backbone and form hydrogen bonds with complementary bases on the opposite strand, holding the two strands together in a double helix structure.
