Question

which statement best describes the components of nucleic acids? they are made up of chains of amino acids. they are made up of carbon, hydrogen, and oxygen only. they are made up almost entirely of carbon and hydrogen. they are made up of nitrogenous bases, sugars, and phosphates.

Explanation:

Nucleic acids (DNA and RNA) are composed of nucleotides. Each nucleotide consists of a nitrogen - containing base, a five - carbon sugar (ribose in RNA or deoxyribose in DNA), and a phosphate group. Amino acids make up proteins. Carbon, hydrogen, and oxygen are part of many biological molecules but do not fully describe nucleic acids. Carbon and hydrogen alone are not the components of nucleic acids.

Answer:

They are made up of nitrogenous bases, sugars, and phosphates.
