NEET Zoology Proteins Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Primary structure | (i) Right-handed helix |
| (b) Tertiary structure | (ii) Collagen |
| (c) Secondary structure | (iii) Folding of polypeptide |
| (d) Quaternary structure | (iv) Amino acid sequence |
a-iv, b-iii, c-i, d-ii
a-iii, b-ii, c-i, d-iv
a-ii, b-i, c-iv, d-iii
a-i, b-ii, c-iii, d-iv
Correct Answer
Detailed Explanation
The primary structure of proteins is defined by the amino acid sequence (a-iv). The tertiary structure involves the folding of the polypeptide chain (b-iii). The secondary structure is characterized by the formation of a right-handed helix (c-i). Collagen is an example of a quaternary structure due to its multimeric nature (d-ii).
