The “primary structure” of a protein refers to:

1. coiling due to hydrogen bonding between amino acids

2. the alpha helix or pleated sheets

3. the side groups of the amino acids

4. the number and sequence of amino acids

Biologists describe the protein structure at four levels. Which level described the sequence of amino acids, i.e., the positional information in a protein?

1. Primary structure

2. Secondary structure

3. Tertiary structure 

4. Quaternary structure 

Read the following statement (A-D) :-

(a) Each protein is a polymer of amino acids.

(b) A protein is a hetero polymer and not a
