Question

question 5 of 10
a nucleotide includes a phosphate group, a sugar, and what other component?
a. a hydrogen bond
b. a nitrogenous base
c. a protein
d. a nucleic acid

Explanation:

A nucleotide is composed of three main parts. The phosphate group is one component. The sugar (either deoxyribose in DNA or ribose in RNA) is another. The third component is a nitrogenous base. Hydrogen bonds are interactions between molecules (like between base - pairs in DNA), not a component of a single nucleotide. Proteins are made up of amino acids and are different from nucleotides. Nucleic acids (like DNA and RNA) are polymers of nucleotides, not a component of a single nucleotide.

Answer:

B. A nitrogenous base
