C) Composed of nucleotides
D) Double stranded molecule and Composed of nucleotides
E) Single stranded molecule and Composed of nucleotides

Accepted Answer

DNA is a double stranded molecule composed of nucleotides. Each nucleotide is made up of a sugar, a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, or thymine). The two strands of DNA are held together by hydrogen bonds between complementary bases (A-T and G-C).
