Schematically represent primary, secondary and tertiary structures of a hypothetical polymer say for example a protein.

Explanation

To represent the primary, secondary, and tertiary structures of a hypothetical protein, we can follow these steps:

### Step 1: Primary Structure
- **Definition**: The primary structure of a protein is the linear sequence of amino acids linked by peptide bonds.
- **Representation**: Draw a straight line of circles or squares, each representing an amino acid. Label them with their respective one-letter codes (e.g., A for Alanine, R for Arginine, etc.). Connect these with lines to represent peptide bonds.

### Step 2: Secondary Structure
- **Definition**: The secondary structure refers to the local folding of the polypeptide chain into structures such as alpha helices and beta sheets.
