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 like DNA and RNA are composed of nucleotides. Each nucleotide contains a nitrogen - containing base, a five - carbon sugar (ribose in RNA and deoxyribose in DNA), and a phosphate group. Chains of amino acids make up proteins. Compounds made of only carbon, hydrogen, and oxygen are common in carbohydrates and some lipids. Compounds made almost entirely of carbon and hydrogen are typical of hydrocarbons in lipids.

Answer:

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