Q. A homopolymer has only one type of building block called monomer repeated 'n' number of times. A heteropolymer has more than one type of monomer. Proteins are heteropolymers usually made of
Biomolecules
Solution:
The function and shape of a protein is affected by sequence of $20$ types of amino acids, each having an amino group $-NH_2$, a carboxylic acid group $-COOH$, a hydrogen atom each attached to carbon located next to $-COOH$ group and a side chain $R$ which varies from one amino acid to other. (It can be hydrogen or an aliphatic group, an aromatic or heterocyclic group).
