Detailed explanation-1: -Uracil is never a part of nucleotide of DNA. It is present in RNA.
Detailed explanation-2: -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-3: -Adenine, thymine, cytosine, and guanine are bases present in DNA. Quinoline, an aromatic compound is not a component of DNA.
Detailed explanation-4: -Tyroxine is not present in nucleotide. Nucleotide consists of adenine, guanine, cytosine, thymine, uracil, molecule of sugar and one of phosphoric acid.
Detailed explanation-5: -D) This is the correct answer. Ribose is found in RNA, and is not found in DNA.
