Detailed explanation-1: -Nucleotides that make the DNA strands contain deoxyribose sugar, phospate molecule and one nitrogenous base out of adenine, guanine, thymine and cytosine. Uracil is never a part of nucleotide of DNA.
Detailed explanation-2: -Answer and Explanation: The correct answer is C. Amino acid. An amino acid is not a component of nucleotide.
Detailed explanation-3: -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.
Detailed explanation-4: -A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).
