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

(a) 20 types of monomers (b) 40 types of monomers

(c) 30 types of monomers (d) only one type of monomer

Answer 1

(a) Proteins are heteropolymers made of about 20 different kinds of monomer, i.e., amino acids. Each of these amino acids is made up of carbon, amino group, carboxyl group, hydrogen and a R-functional group, This variable R- group is what that makes each monomer different from one another.
