Which components make up a nucleotide?

A nucleotide is structured from three fundamental components: a five-carbon sugar (which can be ribose in RNA or deoxyribose in DNA), a phosphate group, and a nitrogen-containing base (which can be adenine, guanine, cytosine, thymine, or uracil). This combination allows nucleotides to link together to form nucleic acids like DNA and RNA, which are essential for storing and transmitting genetic information.

The choice that includes sugar, nitrogen-containing base, and phosphate group accurately reflects the established structure of a nucleotide, making it the correct answer. Understanding this foundational biology is crucial, especially for laboratory animal technologists who often work with genetic material and in research settings.
