(Monoclonal means antibodies of only one specificity while polyclonal means antibodies of different specificities)
25-Hepato lenticular degeneration is observed due to deficiency of which plasma protein?
26-What is the function of complement protein ?
(These are defense molecules present in the plasma in the inactive form, required for pathogenic killing)

(The switch from one class of immunoglobulin to another class is called class switching)
30-How are the light chain and heavy chains linked together?
( By disulphide linkages)
31-What is the function of carbohydrate in the structure of immunoglobulins?
( It is required for the secretion of antibodies by the plasma calls)
