Which is the incorrect association between monomer and polymer? nucleotide - nucleic acid amino acid - polypeptide monosaccharide - polysaccharide nucleic acid - polypeptide?

Option 4 is right option regarding incorrect association.

A nucleotide is a monomer made of sugar, base and phosphate group whereas nucleic acid is a polymer of nucleotide. Thus, this association is correct.

Amino acid is a monomer such as glycine, alanine whereas polypeptide made from association of number of amino acid by creating a peptide linkage to produce a polypeptide.

Monosaccharide is a monomer such as glucose, fructose which associates together to produce polysaccharide such as cellulose made from glucose.

nucleic acid is a polymer of nucleotide whereas polypeptide made from association of number of amino acid by creating a peptide linkage to produce a polypeptide.

Thus, option 4 is right option having incorrect association.
