1.	Question : 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
Answer» 20 types of monomer 40 types of monomer 30 types of monomer only one type of monomer. 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). `H_(2)N-underset(R)underset(\|)overset(H)overset(\|)(C)-COOH`
