Question

Match List - I with List - II.

	List - I		List - II
(a)	Protein	(i)	C=C double bonds
(b)	Unsaturated fatty acid	(ii)	Phosphodiester bonds
(c)	Nucleic acid	(iii)	Glycosidic bonds
(d)	Polysaccharide	(iv)	Peptide bonds

Choose the correct answer from the options given below.

• A. (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)
• B. (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
• C. (a)-(i), (b)-(iv), (c)-(iii), (d)-(ii)
• D. (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)

Answer 1

The Correct Option is B

This question asks you to match biological molecules with their corresponding bonds or structures associated with them. Let's analyze each pair:

1. Protein: Proteins are composed of amino acids linked together by peptide bonds. Hence, Proteins correspond to (iv) Peptide bonds.
2. Unsaturated Fatty Acid: These fatty acids contain one or more C=C double bonds in their structure, distinguishing them from saturated fatty acids. Therefore, Unsaturated fatty acid corresponds to (i) C=C double bonds.
3. Nucleic Acid: Nucleic acids such as DNA and RNA are composed of nucleotides linked by phosphodiester bonds. This connection forms the backbone of nucleic acids. Thus, Nucleic acid matches with (ii) Phosphodiester bonds.
4. Polysaccharide: Polysaccharides are carbohydrates composed of long chains of monosaccharide units bonded together by glycosidic bonds. Therefore, Polysaccharide corresponds to (iii) Glycosidic bonds.

Based on this analysis, the correct matching is:

• (a)-(iv)
• (b)-(i)
• (c)-(ii)
• (d)-(iii)

Therefore, the correct answer is (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii).
