1.	Fragments of antigens are held at the surface of antigen presenting cells by _________________(a) histones(b) antibodies(c) major histocompatibility complex(d) epitopeI have been asked this question at a job interview.My enquiry is from Molecular Basis of Immunity topic in section Immune Response of Cell Biology
Answer» The CORRECT answer is (c) major histocompatibility complex Explanation: Fragments of antigens are HELD at the surfaces of antigen presenting cells (APCs) with the help of MHC (major histocompatibility complex) MOLECULES. The T LYMPHOCYTES are activated with the help of antigen presenting cells.
