Antigenic determinants of an antigen that are recognized by antibody are ______
a) Paratopes
b) Epitopes
c) Isotopes
d) Nondetenninants
Answers
The region on antigen that antibody recognizes are Epitopes, or in other words antigenic determinant. It is 5-8 amino acids on the protein surface. Proteins are 3 dimensional and epitope may be recognized as it exists in solution or native form. Within a protein sequence, you will find either continuous epitopes or discontinuous epitopes. Antigen site is where epitopes and antibodies are bind.
Answer is (B)
Epitopes
Answer:
Antigenic determinants of an antigen that are recognised by antibody are called option b) Epitopes.
Antigen are foreign substances that when enters into a body evokes or generates immune response.
Antigens have specific shapes or determinants that vary in structure called epitopes. They are not same for every antigen and epitopes are recognised by specific antibody of that antigen and thus immune system is provoked by this interaction.
