Question

question 4 of 10
a nucleotide includes a phosphate group, a sugar, and what other component?
a. a nucleic acid
b. a nitrogenous base
c. a protein
d. a hydrogen bond

Explanation:

Nucleotides are the building blocks of nucleic acids, and their structure consists of three core components: a phosphate group, a 5-carbon sugar (deoxyribose or ribose), and a nitrogenous base (adenine, thymine/uracil, cytosine, guanine). Nucleic acids are polymers made of nucleotides, proteins are separate macromolecules, and hydrogen bonds are interactions that hold nucleic acid strands together, not a component of a single nucleotide.

Answer:

B. A nitrogenous base
