The - Helix and - Pleated sheet structures of protein are associated with its:
- a
quaternary structure
- b
primary structure
- c✓
secondary structure
- d
tertiary structure
secondary structure
Step 1: Protein Hierarchy — Primary structure is the sequence of amino acids. Secondary structure refers to local folded shapes like helices and sheets.
Step 2: Hydrogen Bonding — -helices and -pleated sheets are stabilized by hydrogen bonds between the backbone and groups.
Step 3: Result — These specific structural motifs define the secondary level of protein organization. Correct option is (c).
Remember: Tertiary structure involves the further folding of these secondary elements into a 3D globuar or fibrous shape.
