Detailed explanation-1: -A nucleotide is the basic building block of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).

Detailed explanation-2: -Now that we know which of the properties of nucleic acids provided in the question are common to both DNA and RNA, we can answer the question correctly. They are both composed of many repeating nucleotides and contain a phosphate group.

Detailed explanation-3: -Nucleotides simply refer to nitrogenous bases, pentose sugar together with the phosphate backbone. Both DNA and RNA have four nitrogenous bases each-three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine).

Detailed explanation-4: -Nucleotides. Nucleic acids are biological macromolecules which are polymers of repeating monomeric units called nucleotides. A single nucleotide includes a nitrogenous base, a sugar molecule, and a phosphate group. A nitrogenous base with a sugar molecule alone makes up a nucleoside.
