Biomolecular Structures and Components

Steps:

• Statement 1: DNA is a polymer made of nucleotide monomers linked by phosphodiester bonds.
• Statement 2: Glycogen is a polysaccharide formed by glycosidic bonds between glucose molecules.
• Statement 3: Lipids like triglycerides consist of glycerol and fatty acids, not amino acids.
• Correct statements are 1 and 2, matching option B.

Why B is correct:

• B accurately reflects the definitions of DNA as a nucleotide polymer and glycogen as a glucose polymer.

Why the others are wrong:

• A includes false statement 3 on lipid composition.
• C pairs true 1 with false 3, omitting true 2.
• D pairs true 2 with false 3, omitting true 1.

Final answer: B
