Verified step by step guidance

Understand the structure of proteins: Proteins are composed of amino acids linked together by peptide bonds. Each amino acid has a unique side chain that contributes to the protein's structure and function.

Evaluate the options provided: Consider how each modification would impact the ability to model proteins accurately. For example, adding large spheres for water molecules does not directly relate to protein structure, and removing all elements except carbon and hydrogen would oversimplify the model.

Focus on peptide bonds and side chains: Proteins are formed through peptide bonds between amino acids, and the side chains play a critical role in determining the protein's properties. Including components to represent these features would make the model more suitable for proteins.

Consider the importance of bond types: Proteins contain single, double, and other types of bonds. Providing only single-bond connectors would limit the ability to accurately represent the diversity of chemical interactions in proteins.

Conclude that the best modification is to include components for peptide bonds and amino acid side chains, as these are essential for modeling the structure and function of proteins.
