Which of the following is NOT a component of a nucleotide?

Which of the following is NOT a component of a nucleotide?

• A. Phosphate
• B. Sugar
• C. Amino Acid
• D. Nitrogenous Base

Answer: (C)

A nucleotide is the basic structural unit of nucleic acids, such as DNA and RNA. It is comprised of three main components: a phosphate group, a five-carbon sugar (which can be ribose in RNA or deoxyribose in DNA), and a nitrogenous base (which can be one of the four different bases: adenine, thymine, cytosine, or guanine in DNA; or adenine, uracil, cytosine, or guanine in RNA). Amino acids, on the other hand, are the building blocks of proteins and are not involved in the structure of nucleotides. While amino acids and nucleotides are both essential for cellular function, they serve very different roles in biological processes. Therefore, the statement that identifies amino acids as not being a component of a nucleotide is accurate.
