According to molecular biology principles, simple proteins consist solely of amino acids and lack any non-protein components. To answer the question "Which of the following is simple protein?" one must understand this fundamental difference from conjugated proteins, which incorporate additional non-amino acid parts, such as carbohydrates or lipids.

By definition, a protein is classified as "simple" if it yields only amino acids or their derivatives upon hydrolysis, without any non-protein components. These fundamental biological molecules include a wide variety of compounds, such as those that provide structural support, store nutrients, and aid in genetic packaging, which are all excellent examples of simple proteins.

Histones, the proteins that serve as spools for DNA in eukaryotic cell nuclei, are among the least acidic proteins known, primarily because they are rich in positively charged amino acids. A protein's acidity is not determined by taste but by its chemical properties and overall electric charge, a concept central to understanding molecular biology and protein function.

According to scientific analysis, basic proteins are defined by their positive charge at a neutral pH due to a high concentration of basic amino acids such as lysine and arginine. This fundamental property is key to understanding what is the basic protein and its vital functions in biological systems, from DNA organization to enzymatic processes.
