Question

Which of the following statement is FALSE?

1) The backbone of a protein includes both peptide bonds and side chains.
2) Side chains can be either polar or non-polar or aromatic.
3) Variations in the properties of proteins is largely dictated by their unique amino acid sequence.
4) The order of amino acids plays a critical role in dictating the overall protein structure.
5) The internal distribution of side chains is largely dictated by hydrophobic forces.

Answer 1

The FALSE statement is that the backbone of a protein includes both peptide bonds and side chains.

Step-by-step explanation:

The FALSE statement is: The backbone of a protein includes both peptide bonds and side chains.

The backbone of a protein includes peptide bonds, which are formed between the carboxyl group of one amino acid and the amino group of another amino acid. Side chains, also known as R groups, are attached to the alpha carbon of each amino acid in the protein. They can be classified as polar, non-polar, or aromatic.

The correct statement is that the order of amino acids plays a critical role in dictating the overall protein structure, which determines its function. Variations in the properties of proteins are largely dictated by their unique amino acid sequence, and the internal distribution of side chains is largely dictated by hydrophobic forces.
